Forced Convection Cooling Across Rectangular Blocks
Problem Definition:
The problem consists of a wire, to which potential is applied and a plate which is electrically grounded as shown in Fig.1.1 below. Below table 1.1 shows the dimensions and properties used for calculations.

Figure 1.1: Electrostatic precipitator model
Numerical simulations have been performed for a applied voltage of 46200 V. The Fig. 1.2(a) shows the contours of electric potential and Fig. 1.2(b) shows contours of ion charge density.

Variation of electric potential along the plane from wire to plate can be seen in Fig. 1.3(a) and at end plane in Fig. 1.3(b). The results obtained are in good agreement with Long et al. [1].
