Detached eddy simulation (DES) model was used to better capture large vortex structure and unsteady flow feature near cone base. Good base heating results were achieved using proper grid and numerical method. The influence of inflow conditions (like Mach number

Reynolds number) and configuration (bluntness ratio of the cone) on base heating was discussed based on numerical computational results. Compared with base heat flux

base pressure can be predicted more accurately by numerical simulation and the time consuming was shorter. A hybrid method combining numerical simulation with experimental correlation was proposed to predict supersonic turbulent base heating. A review of base heating experiment and correlations for slender cone was presented

and a revised correlation was proposed based on the above simulation results. Compared with the experiment data

the maximum error was 24%

a good result for base heating prediction. This proves that the hybrid method using the revised correlation performs well in predicting supersonic turbulent base heating of slender sphere cone and can meet needs of engineering design.
