Comparative Studies of Aerodynamic Drag Using Inviscid Flow Computation and Newtonian Method at High Speed

R. C. Mehta,
S.B. Tiwari

Abstract: The flow field analysis over various reentry configurations is studied numerically by solving time-dependent compressible Euler equations. The governing fluid flow equations are discretized in spatial coordinates employing a finite volume approach, which reduces the equations to semi-discretized ordinary differential equations. Temporal integration is performed using multi-stage Runge-Kutta time stepping scheme. A local time step is used to achieve steady state solution. The numerical computation is carried ou… Show more
