Abstract : The combined effects of ideal source flow and viscous interaction on the pressure and heat-transfer distributions over hemisphere-cylinders are presented, and a comparison is made with experimental data from two of the AEDC- VKF hotshot tunnels. Ideal gas characteristics solutions for the inviscid flow field over the hemisphere-cylinders were obtained for ideal source flow fields matched to the tunnel geometry. The inviscid and viscous (laminar boundary layer) flow fields were iterated, and the resulting pressure and heat-transfer distributions were compared with the experimental data. Ideal gas analyses made at M = 18 predicted pressure and heat-transfer distributions over a 4-in.-diam model in the 100-in. hotshot Tunnel F, and pressure distributions for a similar model in the 50-in. hotshot Tunnel H were found in reasonably good agreement with the experimental data.
