COMPUTATION OF FLOW FIELD DISTRIBUTION IN ELECTROSTATIC PRECIPITATOR BY EQUAL RESISTANCE SIMULATION

A simple simulating method of computing the flow field distribution in an electrostatic precipitator was introduced. The main idea was to take the air distribution plate as the homogeneously infiltrated plate, and let the resistance of the two type of plates be equal, then the amount of the mesh and the computation time would be largely reduced. The computation data were identical with those of the experiments, thus the simulation computation could replace the model experiment. It is significant for reducing the cost and optimizing the design of the electrostatic precipitator.
