降水条件下台风的定常运动和螺旋斑图
In order to accelerate the convergence speed , we employ the local time step , and implicit residual smoothing methods . finally , we use this method to get the steady solution of the flow around naca0012 and naca4412 airfoil at very low speed and some basic unsteady solution
本文对在低马赫数下绕naca0012翼型和naca4412翼型的定常流场进行了求解，结果和实验基本吻合，并对非定常运动情况进行了初步模拟研究，得出了一些有意义的结果。
The paper depicts the elasticity with euler form and associates the form with depiction of behavior of fluid . the method takes the velocity as basic variables and then derives the left - deformation tensor from the velocity in order to deal with the time - independent motion . at last in this chapter the equations of the finite flow - element are set up from the principle of the virtual work
首先建立流管元的概念，对弹性固体相关的部分采用euler描写，并融入流体行为的描写中；以速度为变量，反推左变形张量，用于处理流固物质的定常运动，给出了控制方程和相应的变分式；以此为基础发展了一套相应的有限流管元算法。
