The drag reduction in spherical spiked blunt body

In this paper hypersonic flow with Mach number 6 around a spike is numerically simulated. The standard k-ε model was used for solving corresponding Reynolds Average Navier-Stoke equations. The computed results show that the drag coefficient of the spiked blunt body is reduced respect with no spiked body. Our numerical calculations also agrees with corresponding experimental work. Moreover the computed shock stand-off distance is in reasonable agreement with other related works.
