Because the electrical equations in electrostatic precipitator are analogous to the equations used to describe fluid flow,the downwind scheme in computational fluid dynamics is introduced to solve the current continuity equation in the case of positive corona,and the relevant upwind scheme is applied in the case of negative corona.

Hyperbolic grid generation using upwind scheme;

Based on upwind scheme and Runge-Kutta method,two new difference schemes improved for solving the convection equation are introduced.

Then, the values of nodes in expanding band are updated by upwind scheme once or twice in different orders.

Characteristic analysis of the upwind scheme;

Because the electrical equations in electrostatic precipitator are analogous to the equations used to describe fluid flow,the downwind scheme in computational fluid dynamics is introduced to solve the current continuity equation in the case of positive corona,and the relevant upwind scheme is applied in the case of negative corona.

Through comparing different results of simulating shock reflection flow over a forward step using different schemes including Roe and van Leer schemes,the advanced upwind scheme(AUSM+) is fully studied in terms of its resolution and efficiency for shock waves,expansion vaves,contact discontinuities and their interactions.
