A transient , three - dimensional , non - isothermal and two - phase mathematical model based on computation fluid dynamics was developed to describe the dynamic process of pemfc 摘要為描述質(zhì)子交換膜燃料電池的動態(tài)過程,發(fā)展了一個基于計算流體動力學的非穩(wěn)態(tài)、非等溫的三維兩相流數(shù)學模型。
The curved grids are generated by using the transfinite interpolation and the so - called multiblock techniques that originally developed for computation fluid dynamics . the curved grid is taken to constitute a generalized curvilinear system 該方法結(jié)合了多塊映射和超限插值技術(shù),這項技術(shù)出自計算流體力學,它可使產(chǎn)生的網(wǎng)格網(wǎng)線沿著地下所有界面變化。
Local discomfort is an important reason of human discomfort in winter air condition room . basis of the method of computation fluid dynamics , through phoenics computation simulation , with the premise that flow and temperature distribution is basically consistent , the article further analyzes the distribution regulation of indoor parameters in air condition room and reflects the characters which ca n ' t give out and reveal only by experience and practical measurement on the spot . at the same time , it provides some very excellent forecast and evaluation methods by use of cfd 由于冬季空調(diào)房間的熱特性的影響,局部不適是冬季空調(diào)房間內(nèi)的人體不舒適的重要原因,基于計算流體動力學方法,通過phoenics的計算模擬,在流動和溫度分布的基本規(guī)律相符的前提下,進一步細化了空調(diào)房間室內(nèi)參數(shù)分布的規(guī)律性,反應了僅憑經(jīng)驗和現(xiàn)場實測所不能給出和揭示的特點,同時運用cfd工具為工程實踐提供了很好的預測和評價手段。
