1.
Based on our previous fourth-order compact difference scheme for the 3-D steady convection diffusion equation,a high-order compact implicit difference scheme for the 3-D unsteady convection diffusion equation is directly obtained.
将已经建立的求解三维定常对流扩散方程的高阶紧致差分格式直接推广到三维非定常对流扩散方程的数值求解,时间导数项利用二阶向后欧拉差分公式,所得到的高阶隐式紧致差分格式时间为二阶精度,空间为四阶精度,并且是无条件稳定的。
补充资料：对流扩散
分子式：
CAS号：
性质：在湍流流体中，物质的传递既靠分子扩散也靠涡流扩散，合称对流扩散。
