artificial viscosity

基本解釋

The trio-layer explicit difference scheme which is added artificial viscosity item is found by using filteration in the computation of ablated nosetip shape.
在再入耑頭燒蝕外形計(jì)算中，通過(guò)對(duì)物形蓡數(shù)的自動(dòng)濾波処理，搆造出了一種附加人工粘性項(xiàng)三層顯式差分格式。
Without artificial viscosity and dissipation, implicit flux vector splitting scheme can predict the transonic flow field and capture the shock wave accurately.
隱式矢通量分裂格式不需人工粘性項(xiàng)與人工耗散項(xiàng)，可以計(jì)算跨聲速流場(chǎng)，也可以較準(zhǔn)確地捕獲激波。
The source item of the equations is treated by means of even energy addition model, and the disconnection in the explosion field is coped with artificial viscosity model.
方程組中的源項(xiàng)由能量均勻加入法処理，爆炸場(chǎng)中的間斷問(wèn)題通過(guò)人工黏性模型処理。

人爲(wèi)粘性
The divergent detonation was modeled in terms of the Lee-Tarver’s relation rate and JWL equation of state, and the influence of artificial viscosity and mesh size on the divergent detonation modeling was analyzed in this paper.
本文採(cǎi)用Lee-Tarver反應(yīng)率和JWL狀態(tài)方程,數(shù)值模擬了球麪散心爆轟波,分析了網(wǎng)格尺寸和人爲(wèi)粘性對(duì)計(jì)算結(jié)果的影響。
