Abstract

Athree-dimensionalcomputationmodelwithactualsizeswasdevelopedbychoosingtherecoilbrakeofacertaingunastheresearchobject. Dynamicmeshesandslidingmeshestechniqueswere usedtonumericallycalculatethethree-dimensionalflowfieldinsidetherecoilbrakeattheactualrecoilingvelocityofthegun. Thepressuresofthedifferentchambersintherecoilbrakewerecalculated byusingthestandardk- model,theRNGk- modelandtherealizablek- model,respectively.And thecalculatedpressureswerecomparedwiththeexperimentalresults.Comparisonsshowthatthe pressurescalculatedbythestandardk- modelareinthebestagreementwiththeexperimentalresults.
