A mathematic model for cooling water discharge to forked bays is established by using the boundary fitted orthogonal coordinate system to simulate the complex boundaries , the full implicit coupled solution model to discrete the base equations , and the matrix chase - after method to solve the algebraic equations 摘要采用正交邊界擬合坐標(biāo)變換模擬復(fù)雜的邊界,全隱式耦合模型離散基本方程,矩陣追趕法求解代數(shù)方程組,建立了分叉型海灣溫水排放數(shù)學(xué)模型。
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(chǔ)上,采用有限體積方法和完全隱式的耦合算法,通過(guò)求解帶realizablek -兩方程湍流模型的多組分、有反應(yīng)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?qū)?fù)雜形狀的三維噴管和光腔進(jìn)行數(shù)值模擬的三維程序,解決了連續(xù)波df hf化學(xué)激光器增益發(fā)生器設(shè)計(jì)缺乏三維數(shù)值模擬工具的問(wèn)題,并用該工具解決了cr程序無(wú)法實(shí)現(xiàn)的hylte等復(fù)雜三維噴管流場(chǎng)的理論模擬問(wèn)題。
