New Method to Solve Flow Equation using Total Variation Diminishing(TVD) Schemes with Third and Fourth Order Accuracy TVD三阶和四阶格式求解渗流方程新方法
New five point total variation diminishing ( TVD ) schemes with third and fourth order accuracy in space and second order accuracy in time were constructed by applying the Taylor series theory and the TVD sufficient conditions. 利用Taylor级数理论和总变差减小(TVD)格式的充分条件构造了时间二阶、空间五点三阶和四阶新TVD格式。
The finited volume method and a total variation diminishing ( TVD ) numerical scheme were used to solve the axisymmetric Euler equation, which was utilized to simulate the Micro Pressure Wave discharged from the tunnel exit when a train entered a tunnel at high speed. 采用有限体积法和TVD性质的差分格式相结合求解轴对称欧拉方程的方法对高速列车通过隧道时在隧道出口区域产生的微压波问题进行了数值研究。
