超音速射流流场湍流模型适应性研究
Study on Adaptability of Supersonic Jet Flow Turbulence Model
摘要
Abstract
To study and analyze the adaptability of five kinds of turbulence model coming with fluent for supersonic jet systematically ,the five kinds of turbulence model were used for Mach 1.7 nozzle on numerical simulation ,the distribution of velocity and temperature along axial direction was obtained ,and compared with experimentally measured values .The comparative results show that :the results acquired using standard k_εmodel and the standard k_ωmodel ,compared with ex_perimental results ,have big deviation ,w hile the deviation is much smaller w hen using RNG k_εmodel ,realizable k_εmodel and SST k_ωmodel .The comparison with experimental results both in the near field and far field ,shows that the simulation result achieved by SST k_ωmodel simulation has the highest degree in accordance with experimental results ,so the final conclusion was a_chieved:SST k_ωsimulation model is most suitable for the jet simulation for Mach 1.7 nozzle .关键词
