界面速度 boundary velocity
- 结果显示,在凝固过程中界面速度和界面溶质浓度都存在着很大的波动。
And the fluctuation of the interface velocity and solute concentration during the solidification is also predicted. - 针对复杂区域中流动计算的SIMPLE算法,在选用不同的速度分量作为求解变量和离散体元的界面速度时,进行了算法收敛速度及收敛准确性的对比分析。
With the choices of dependant variables and cell face velocity, the convergency speed and computational accuracy of SIMPLE algorithm employed in the computation of complex flows are analyzed. - 该算法的特点是显式处理界面速度中的压力交叉导数项,得出压力与压力修正方程,使得压力及压力修正值与界面逆变速度直接耦合。
The main feature of the algorithm is that the pressure and pressure correction equations are obtained by explicitly treating pressure cross-derivatives terms in interface contravariant velocities.
