Hypersonic flow past slender bodies in dispersive hydrodynamics
The problem of two-dimensional steady hypersonic flow past a slender body is formulated for dispersive media. It is shown that for the hypersonic flow, the original 2+ 0 boundary-value problem is asymptotically equivalent to the 1+ 1 piston problem for the fully nonlinear flow in the same physical system, which allows one to take advantage of the analytic methods developed for one-dimensional s...
متن کاملFlow Simulation over Re-Entry Bodies at Supersonic & Hypersonic Speeds
In the present paper, flow simulations are carried on two design configurations of re-entry vehicles, FIRE II and OREX using commercial flow solvers. The purpose of the paper is to present the effect of flight attitude upon the aerodynamic characteristics of an Apollo shaped re-entry capsule. This paper exemplifies the importance of the aerodynamic forces effect on the motion of re-entry vehicl...
متن کاملSome aspects of hypersonic flow over power law bodies
This study concerns the hypersonic flow over blunt bodies in two specific cases. The first is the case when the Mach number is infinite and the ratio of the specific heats approaches one. This is sometimes referred to as the ‘Newtonian limit’. The second is the case of infinite Mach number and very large streamwise distance from the blunt nose with a strong shock wave, or the ‘blast wave limit ...
متن کاملAnalytic Solution for Hypersonic Flow Past a Slender Elliptic Cone Using Second-Order Perturbation Approximations
An approximate analytical solution is obtained for hypersonic flow past a slender elliptic cone using second-order perturbation techniques in spherical coordinate systems. The analysis is based on perturbations of hypersonic flow past a circular cone aligned with the free stream, the perturbations stemming from the small cross-section eccentricity. By means of hypersonic approximations for the ...
متن کاملAugmented Burnett-Equation Solutions over Axisymmetric Blunt Bodies in Hypersonic Flow
We obtained augmented Burnett-equation solutions and conducted some preliminary studies on the extent to which the Burnett equations can be used in estimating the departure from the NavierStokes model for hypersonic flow over axisymmetric blunt bodies. The augmented Burnett equation solutions were restricted to the flow inside the bow shock in the stagnation region because of the uncertainty of...
