  Author(s): Wan T and Liu CM Wan T and Liu CM
  
  Pressure drag and aeroheating stirred by the shock wave is the main challenge of hypersonic flight, and blunt body is always the principle configuration at hypersonic flow regime for heat distribution, but it would induce substantial drag. Therefore, both aerospikes and aerodisks can be efficiently utilized as a mean for drag reduction. In this work, we investigate the effect of different geometric shapes of aerospikes with various disk gap widths on drag reduction. Accordingly, a series of numerical simulation work was implemented to find the behaviour as to hypersonic flow over aerospiked blunt bodies. Moreover, the drag reduction efficiency of spiked blunt bodies would be optimized via the Kriging method. For the models we studied, we found that the drag on the spiked blunt bodies is much lower than the spike off one. The drag reduction efficiency especially would be predominated b.. View More»
