矩形弯头消声器的阻力问题

axijet

问题描述： 矩形弯头内弧R270mm,外圆弧R900mm,进出口630mm宽,弯头和上下游管道1000mm宽， 630mm高。空气进10m/s. I built a 3D mold with 5D upstream and 10D downstream duct length. I have tried standard k-e, realizable k-e, RNG k-e,RSM models and the pressure drops I got are quite close but only around 50% of tested pressure drop.
Your comments and helps are highly appreciated.[br][br][以下内容由 axijet 在 2006年08月21日 07:57am 时添加] [br]
