The quantification of mitral stenosis by using a new color Doppler flow convergence method was evaluated, and compared with two -dimensional echocardiography, pressure half- time and combined method.
The method of mass flux correction is introduced with success in order to accelerate convergence in iteration of velocity and pressure calculation.
为了加速速度和压力迭代的收敛性成功地引入了质量流量校正法。

Numerical calculations for sudden expansion pipe flow have shown that the secondary pressure correction method can clearly accelerate convergence, improve accuracy and save C. P. U time.
