In this paper, a three - dimensional ( 3d ) program for the three - dimensional reactive flow fields of complicated geometric nozzle, which governed by the compressible full navier - stokes equations with realizable k - s turbulent model, has been upbuilt by using full implicit couple arithmetic and fvm ( finite volume method ) based on understanding and assimilation of a two - dimensional program group of cr ( chamber - radon ). the new program fulfils the urgent need of numerical tools for simulating three - dimensional reactive flow - fields of hylte ( hypersonic low temperature ) and other latest nozzles, for which cr is out of action in simulation, and can be applied to simulate other chemical laser system, such as chemical oxygen iodine laser ( coil ), overtone fluoride hydrogen, all - gas iodine laser, and so on. furthermore, some related topics about nozzles design and engineer ing also have been discussed
本文在二維cr ( chamber ? radon )程序研究的基礎上,採用有限體積方法和完全隱式的耦合演算法,通過求解帶realizablek -兩方程湍流模型的多組分、有反應的三維完全納維埃?斯托克斯( n ? s )控制方程,建立了一套能夠對復雜形狀的三維噴管和光腔進行數值模擬的三維程序,解決了連續波df hf化學激光器增益發生器設計缺乏三維數值模擬工具的問題,並用該工具解決了cr程序無法實現的hylte等復雜三維噴管流場的理論模擬問題。
