Hypersonic flow over a six-finned configuration
Tóm tắt
Experimental data of the flow field over a six-finned configuration are compared with computations from an inviscid Euler code and a parabolized Navier-Stokes (PNS) code to assess their accuracy. Surface oil flow patterns, surface pressures, and flow field pilot surveys are presented. The PNS computations are in good agreement with the measurements in the inviscid regions. Differences are noted in the viscous regions possibly due to nose tip bluntness effects and the associated entropy layer.
