Computation of Electrical Conditions Inside a Wire-Plate Electrostatic Precipitator Using an Unstructured Finite Volume Method

Abstract

In this paper, an unstructured cell-centered second-order accurate finite volume method is presented for the computation of electrical conditions inside wire-plate electrostatic precipitators. The potential equation was discretized using a second-order accurate scheme by invoking a new type of special line-structure. The space-charge density equation was discretized using an upwind scheme, and solved using a direct method. The local gradients are reconstructed by a Green-Gauss reconstruction method. The method can deal with complex geometries by using unstructured meshes. Numerical experiments show that the predicted results agree well with the existing experimental data.
