Analytical solution for the Eulerian andLagrangian particle models are usually obtained just for stationary conditions and by assuming strong assumptions on the wind speedprofiles and turbulent parameters. In the analytical solutions of the diffusion - advection equation, authors assumed constant wind...
3) diffusion-convection-reaction equation 扩散对流反应方程 1. For a convection-dominated diffusion-convection-reaction equation,some new higher order regular estimates about its true solution are derived firstly. 针对对流占优的扩散对流反应方程,首先得到关于真解的一些新的高阶正则性估计。

The first step in the numerical solution of these equations is the discretization of the space derivatives. By this fundamental step the partial differential equation is transformed into a system of ordinary differential equations. In this report, we show that study of the space differentiation can ...
