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，通過對物形蓡數(shù)的自動濾波処理，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，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，爆炸場中的間斷問題通過人工黏性模型処理。

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)粘性對計(jì)算結(jié)果的影響。
