帶有熱源的流場仿真

1、注：小弟剛學workbench沒多久，有許多地方還不怎么熟。該案例是小弟自己摸索出來的，里面還有好多知識不是很清楚，所以寫的也比較水，希望各位大神看了以后提出寶貴的意見，小弟不勝感激。希望能和大神們多多交流，這樣才會有長遠進步。一、帶有熱源的流場仿真熱源材質(zhì)為Copper（銅），中間隔熱材料為wood（木），米用冷卻水冷卻，水溫為10C流速為0.0001m/s。周圍大氣環(huán)境為20Co二、三維建模：黃色為熱源內(nèi)徑為24mm外徑為30mm，綠色為隔熱材料內(nèi)徑為20mm外徑為24mm,內(nèi)腔為流體區(qū)域直徑為20mm,其長度都為60mm。另存為x_t格式（可以導入到workbench里面）三、冷卻仿真：
