FLUENT噴霧模擬具體步驟

1、dispersionangle參數很重要設置的是6太小了選擇離散相模型DPM（拉格朗日離散粒子多相流）DiscretePhaseModel面板中的UnsteadyParameters屬性框中激活了UnsteadyTracking選項，在瞬態(tài)流動中考慮相間耦合計算，在每一個迭代時間步長內,依據在NumberOfContinuousPhaseIterationsPerDPMIteration設定的迭代步數進行顆粒軌道的迭代計算。液滴破碎模型：泰勒類比破碎模型FLUENT提供兩種霧滴破碎模型：泰勒類比破碎（TAB）模型和波致破碎模型。本文選自泰勒類比破碎模型。DiscretePhaseModel-S
