  • Based on three-dimensional Reynolds averaged Navier-Stokes equations and low Reynolds number k-ε equations, a numerical program to simulate the 3D flowfield of aerospike nozzle was developed by employing two-order Non-oscillatory and Non-free-parameters Dissipative finite difference scheme. The 3D flowfield of a linear aerospike nozzle and a tile-shaped aerospike nozzle at different flight altitude were predicted. The results indicate that the pressure distribution on the plug of a tile-shaped aerospike nozzle have the advantage of load uniformity, and the cylindrical plug can load more than the planar plug under the same conditions.
