Abstract : Experimental data of the flow field over a six-finned configuration are compared with computations from an inviscid Euler and a parabolized Navier-Stokes (PNS) code to assess their accuracy. The experiments were conducted with a smooth and a grooved cylinder in a hypersonic (M=6.5) wind tunnel. Surface oil flow patterns, surface pressures, local heat flux rates and flow field pitot surveys are presented. The PNS computations are in good agreement with the measurements in the viscid regions. However, significant differences are noted in the viscous regions possibly due to nose tip bluntness effects and the associated entropy layer. Keywords: Hypersonic, Aerodynamics, Fluid mechanics, Navier Stokes, Code validation, Finned configuration, Experiment.
