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.
在再入端頭燒蝕外形計算中，通過對物形參數的自動濾波處理，構造出了一種附加人工粘性項三層顯式差分格式。
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與人工耗散項，可以計算跨聲速流場，也可以較準確地捕獲激波。
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.
方程組中的源項由能量均勻加入法處理，爆炸場中的間斷問題通過人工黏性模型處理。

人為粘性
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.
