Comparison of Lift and Drag Forces for Some Conical Bodies in Supersonic Flow Using Perturbation Techniques
Numerical methods are not always convergent especially in higher velocities when shock waves are involved. A comparison analysis is performed to study the supersonic flow over conical bodies of three different cross sections circular, elliptic and squircle (square with rounded corners) shaped using Perturbation techniques to find flow variables analytically. In order to find lift and drag forc...
متن کاملDynamical separation of spherical bodies in supersonic flow
An experimental and computational investigation of the unsteady separation behaviour of two spheres in Mach-4 flow is carried out. The spherical bodies, initially contiguous, are released with negligible relative velocity and thereafter fly freely according to the aerodynamic forces experienced. In experiments performed in a supersonic Ludwieg tube, nylon spheres are initially suspended in the ...
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 کاملExperimental Investigations of Supersonic Flow around a Long Axisymmetric Body
A series of supersonic wind tunnel tests on an ogive-cylinder body were performed to investigate the pressure distribution, the boundary layer profiles, and the flow visualization at various angles of attack. All tests were conducted in the trisonic wind tunnel of the Imam Hossein University. The theoretical shock angle at different model positions compared well with those we obtained via Schi...
متن کاملFar Field Scattering from Bodies of Revolution
By use of approximations based on physical reasoning radar cross-section results for bodies of revolution are found. In the Rayleigh region (wavelength large with respect to object dimensions) approximate solutions are found. Examples given include a finite cone, a lens, an ellipticogive,.a spindle and a finite cylinder. In the physical optics region (wavelength very small with respect to all r...
