An axisymmetric near wake analysis using rotational characteristics by Mauro Pierucci( Book )

2 editions published in 1970 in English and held by 2 WorldCat member libraries worldwide

The near wake of a cone in a hypersonic stream is analyzed by simultaneously solving the inviscid region and the viscous shear layer. The inviscid region is solved by the use of rotational axisymmetric characteristics. It is assumed that viscosity and heat transfer play an important role only within a region bounded by streamlines which at the trailing edge of the cone are for the most part in the subsonic portion of the boundary layer. This region, termed the shear layer, lies between the dividing streamline (or centerline) and the basic streamline. The solution to the inviscid region is obtained by specifying conditions along the characteristic line originating at the shoulder of the cone, and by specifying the pressure distribution along a free surface (basic streamline) taken to be the streamline which at the shoulder of the cone separates the supersonic from the transonic and subsonic portions of the boundary layer. The pressure distribution along the basic streamline is iterated until the mass flow, momentum, and energy in the shear layer are consistent with the location of the dividing streamline and with the initial conditions at the edge of the cone. Profiles for pitot pressure, static pressure and stagnation enthalpy are presented and compared with experiments at different downstream locations. The shape and strength of both the lip and recompression shock are also shown. Both sets of results are seen to be in very good agreement with the experimental results available. (Author)
The laminar boundary layer with hydrogen injection including multi-component diffusion by Paul A Libby( Book )

2 editions published in 1964 in English and held by 2 WorldCat member libraries worldwide

There is treated a laminar flow which is simple from the fluid mechanical and chemical points of view but which involves multi-component diffusion and relatively accurate transport properties. Thus a similar boundary layer with hydrogen injection and with chemical behavior idealized according to the flame sheet model is considered. On the basis of several numerical examples it is found that there is predicted by the present analysis boundary layer behavior significantly different from that given by analyses with simple transport; e.g., the velocity profiles with hydrogen injection resemble suction profiles because of the reduction in the rho mu product. Accordingly, the accuracy of existing analyses involving species with a spectrum of molecular weights and employing the assumption of simple transport properties would appear doubtful. (Author)
Compliant-Coating-Fluid Interaction: Coating Shear Waves in Stationary Fluid( Book )

1 edition published in 1982 in English and held by 1 WorldCat member library worldwide

The objective of this work is to study the transfer of energy between an elastic solid coating, a viscoelastic non-homogeneous layer and the surrounding viscous fluid. The particle displacements and stress distributions in the solid and the fluid are analyzed. The motion at the lower boundary of the elastic solid is assumed given. The effect of coating properties, transition layer thickness and frequency are obtained. (Author)
Compliant-Coating-Fluid Interaction: Coating Longitudinal Waves in Stationary Fluid( Book )

1 edition published in 1982 in English and held by 1 WorldCat member library worldwide

The presence of a thin non-homogeneous layer at the interface of an elastic and a fluid medium can alter the energy exchange between the two media. In this report the effect of the transition layer upon the propagation of one-dimensional longitudinal waves is analyzed. The motion of the lower boundary of the elastic layer is assumed known and the energy radiation into the fluid is obtained
Effect of an Inhomogeneous Transition Layer on the Response of a Compliant Layer due to a Shear Fluid Disturbance( Book )

1 edition published in 1983 in English and held by 1 WorldCat member library worldwide

The amount of interaction between a fluid and a compliant coating is studied for a one dimensional shear fluid disturbance. A thin inhomogeneous viscoelastic layer is located at the interface between the fluid and the coating. The fluid is assumed to have no mean flow field. The effect of different coating properties, thickness of compliant coating and of transition layer as well as the frequency of oscillations are analyzed. (Author)
Thermo-Vibro-Acoustic Loads and Fatigue of Hypersonic Flight Vehicle Structure( )

1 edition published in 2009 in English and held by 0 WorldCat member libraries worldwide

Research was completed in 1989. A three-phase study of the "Thermo-Vibro-Acoustic Loads and Fatigue of Hypersonic Flight Vehicle Structure" is being performed by Rohr Industries, Inc., McDonnell Douglas Corporation and Science Applications International Corporation. The Phase I Study (AFWAL-TR-89-3014) evaluated various hypersonic vehicle designs and identified potential fatigue related issues resulting from high temperature vibroacoustic loads. This report contains the results of Phase II. A typical trajectory calling for ascent to orbit in 15 minutes and a generic Blended Wing Body vehicle design have been identified. Detailed designs for forebody, ramp, stabilizer, and nozzle skin panels are developed. Aerothermal and acoustic loads are determined. Analysis is made to determine temperatures, mean stress, and dynamic stress in panels. The results show that aeroacoustic loading will be critical for the design of ramp, stabilizer and nozzle vehicle skin panels
