On onedimensional channel flow in the presence of a magnetic field by William B Bush(
Book
)
4 editions published in 1959 in English and held by 5 WorldCat member libraries worldwide
The differential equations for the onedimensional, varyingarea channel flow of a perfect gas in the presence of a magnetic field are formulated under the restriction that the electric field be zero. The solutions are presented in analytical and graphical form. The results show that with increasing magnetic field the sonic point moves downstream from the channel's throat and that, in general, a larger exit area is needed to obtain a given supersonic flow Mach number.

On diffusion flames in turbulent shear flows by William B Bush(
Book
)
2 editions published in 1973 in English and held by 2 WorldCat member libraries worldwide
Predictions of the timeaveraged mass fraction profiles for a turbulent diffusion flame, which immediately imply the rate of product formation, are readily made, provided the timeaveraged profiles for a passive scalar in the same flowfield and also the probability distribution function for the fluctuating states of the passive scalar in the same flow are known. While recently proposed closures for the timeaveraged conservation laws permit the timeaveraged profiles to be determined analytically with adequate accuracy, the probability distribution function is likely to require experimental measurement

The hypersonic approximation for the shock structure of a perfect gas with the sutherland viscosity law by William B Bush(
Book
)
2 editions published in 1962 in English and held by 2 WorldCat member libraries worldwide
The classical NavierStokes treatment of the shock wave strucure is investigated for a perfect gas with constant specific heats. The viscosity of the gas is presribed according to the Sutherland law. he Prandtl number is 3/4. The limiting forms of the solution as the upstream flow Mach number approaches infinity, with all other parameters held fixed, is studied. two distinct asymptotic seies are found for the portions of the shok adjacent to the uniform regions upstrem and downstream of the shok and these expansions re matched in an intermediate region of common validity. The leading terms of a uniformly valid expansion are otained by combining elements from both expansions. Special attention s given to the entropy and the entropy production rate in the shock wave

The Structure of Multiple Diffusion Flames for a TwoStep Chain Reaction by William B Bush(
Book
)
2 editions published in 1973 in English and held by 2 WorldCat member libraries worldwide
The low speed deflagration of initially unmixed gaseous reactants under an irreversible twostep chain reaction is examined. Both equilibrium burning, in which two separated flames of zero thickness arise, and nearequilibrium burning, in which two spatially separated flames of small but finite thickness arise, are studied by limit process expansion techniques. Two timedependent twodimensional flows are examined: the first is diffusion flow; and the second is counter stagnation flow. The latter flow, in which there is an impressed finite strain parallel to the flame, such that the flame, itself, is longitudinally stretched, is discussed as elucidating the characteristics of combustion in turbulent shear flows.

Asymptotic Analysis of the Turbulent Boundary Layer with Zero Wall Stress by William B Bush(
Book
)
2 editions published in 1973 in English and held by 2 WorldCat member libraries worldwide
The (socalled) continuously separating incompressible turbulent boundary layer, where the impressed pressure gradient is such as to produce zero stress at the wall, is studied by means of secondorder closure of the Reynolds timeaveraged equations. The closure employs an eddy viscosity which is the product of two properties of the turbulence: the mean turbulent kinetic energy and the local integral scale of the turbulence; each of these properties is described by a transport equation balancing convection, production, diffusion, and dissipation. Limit process expansions are adopted in the limit of large turbulent Reynolds number to elucidate a twolayer structure. (Modified author abstract)

Asymptotic Analysis of Turbulent Channel Flow for Mean Turbulent Energy Closures by William B Bush(
Book
)
2 editions published in 1972 in English and held by 2 WorldCat member libraries worldwide
The Reynolds timeaveraged equations are adopted for fully turbulent twodimensional flow of an incompressible fluid through a channel with plane smooth walls. Closure is effected by means of socalled secondorder methods based on the conservation of mean turbulent kinetic energy. In particular, generalizations of the turbulent shear flow models due to Bradshaw, Ferriss, and Atwell and to Spalding and coworkers, are adopted as representative of recent differential closure models. The models are treated in the limit of large turbulent Reynolds number by means of limitprocess expansions. (Author)

On the newtonian hypersonic stronginteraction theory for flow past a flat plate by William B Bush(
Book
)
2 editions published in 1966 in English and held by 2 WorldCat member libraries worldwide
The viscous hypersonic flow past the leading edge of a sharp flat plate, whose surface is parallel to an oncoming uniform flow, is analysed on the basis of a continuum model consisting of the NavierStokes equations and the velocityslip and temperaturejump wall boundary conditions. It is assumed that the model fluid is a perfect gas having constant specific heats, a constant Prandtl number whose numerical value is order unity, and a normal viscosity coefficient varying as a power of the absolute temperature. Limiting forms of the solutions for such a flow are studied as: (1) the freestream Mach number, M, goes to infinity; (2) the freestream Reynolds number based upon the distance from the leading edge goes to infinity; and (3) the 'Newtonian parameter' goes to zero.

Asymptotic Analysis of Turbulent Channel Flow for MixingLength Theory by William B Bush(
Book
)
2 editions published in 1972 in English and held by 2 WorldCat member libraries worldwide
Limit process expansion techniques are used to analyze fully developed turbulent incompressible flow in an infinitely long channel with plane parallel walls. Closure of the Reynolds timeaveraged equations of motion is effected through the introduction of an eddy viscosity linearly proportional to the mean rate of strain, such that the Reynolds stress is quadratic in the mean rate of strain: the closure is a generalization of mixinglength theory. Expansions are carried out in the limit of the turbulent Reynolds number going to infinity, where the turbulent Reynolds number is the ratio of the eddy viscosity to the molecular viscosity. (Author)

Design of a suctiontype, intermittent wind tunnel for supersonic and subsonic testing(
Book
)
1 edition published in 1958 in English and held by 1 WorldCat member library worldwide
Theoretical experimental investigations previously indicated the feasibility of ionizing an aerodynamic boundary layer by means of a gaseous discharge. In the presence of magnetic fields, sufficiently large forces acting on the air in the boundary layer can be developed. The principles involved are those of magnetohydrodynamics, together with those of the electrical breakdown of gases. To study the application of these techniques of boundary layer control, a wind tunnel is required. A detailed description is presented of wind tunnel and component designs. (Author)

Magnetic field effects on bow shock standoff distance(
Book
)
1 edition published in 1958 in English and held by 1 WorldCat member library worldwide
Combined theoretical and experimental investigations were carried out to find the effects of a magnetic field on the shock wave standoff distance of an unyawed blunt body of revolution. Under the experimental conditions, the standoff distance was found to increase with increasing field strength. The predicted behavior agreed quite well with the experimental findings

Asymptotic Analysis of a Turbulent Boundary Layer in a Strong Adverse Pressure Gradient(
Book
)
1 edition published in 1987 in English and held by 1 WorldCat member library worldwide
The structure of an incompressible turbulent boundary layer subjected to a strong adverse pressure gradient is studied by means of an asymptotic analysis of the Reynolds timeaveraged equations. Limitprocess expansions developed in the limit of large Reynolds number reveal a relatively thick nondefect layer in the outer region of the boundary layer near the exterior inviscid flow, and a relatively thin layer near the wall. To leading orders of approximation, the momentum balance involves convection, pressure gradient, and turbulent stress in the outer layer, and pressure gradient, and turbulent and viscous stresses in the inner layer. The asymptotic expansions for these two layers are matched in an arbitrary intermediate region, wherein the streamwise velocity has a squareroot dependence and the Reynolds stress has a corresponding linear dependence on the normal coordinate. The leadingorder approximations for the outer and inner layers give rise to similarity formulations, from which appropriate similarity formulations for the distinguished intermediate layer have been identified and developed. These latter formulations are employed to analyze available experimental data

Compressible flat plate boundary layer flow with an applied magnetic field(
Book
)
1 edition published in 1958 in English and held by 1 WorldCat member library worldwide
The laminar boundary layer equations are formulated and solved for a flat plate in high speed compressible air flow where equilibrium dissociation and ionization are assumed and where there is an applied magnetic field having its component normal to the plate proportional to 1/ square root of x. The skin friction and heat transfer characteristics are determined for free stream velocities of up to 17,500 meters/sec and magnetic fields of up to about 1 Weber/ sq m. The results show that the skin friction and heat transfer at a given free stream velocity decrease with increasing magnetic field strength and the percentage reduction is constant along the length of the plate. They also exhibit the same hysteresis behavior as was first found in the case of magnetoaerodynamic Couette flow; however, for the flat plate the hysteresis effect disappears at a higher Mach number. Furthermore, it was found that the reduction in heat transfer with increasing field strength is opposite in behavior from that for Couette flow. (Author)
