Abstract

Aerospoke nozzle is one kind of the converging-diverging nozzle that are more effective than of the Bell nozzle. The Aerospike Nozzle have high efficiency in the all Number of Pressure Ratio (NPR). Also, the usability as a vector Thrust is the other benefits of the Aerospike Nozzle. The disadvantage of the Aerospike Nozzle it’ s heavier than as the Bell nozzle and the Aerospike Nozzle requires cooling system. There are afew studies about the Aerospike Nozzles and the use of this type of nozzles requires more experimental and theoretical studies. In this study reported the results of numerical simulation an axisymmetric Aerospike Nozzle. In This study used a structure grid and the K-ε turbulence model. The effected of NPR was investigated and the NPR varied between 2 to 50. The results show linear relation between NPR and nozzle Mass Flow Rate. In the last part of this study the effected of the spike length was studied. The four defferent spikes was modeled by 20, 40, 60 and 80 percent length of the first spike length in 10 NPR and results show the cutting more than 40 percent length of the spike effect in flow quality.
