【 摘 要 】

A series of numerical simulations are conducted on bi-cone shaped axisymmetric geometries using ANSYS FLUENT commercial code. Eight bi-cone geometries were simulated with first cone half-angle fixed at 25° and varying the second cone half-angle varying from 10° to 45° with an increment of 5°. The simulations were conducted in hypersonic flow regime at three different Mach numbers of 6, 8, 10 with geometries approximated as 2-D axisymmetric. Shock interactions observed essentially fall in the TYPE VI and TYPE V category. The simulations accurately predicted these shock interactions, the size of flow separation regions, the surface pressure, and density variations across the geometries considered. It is observed that when the second cone angle is greater than the first cone angle larger values of pressure and heat flux were encountered at flare angle whereas when the second angle is less than the first cone angle, smaller values of pressure and heat flux were encountered at the second cone.
