Numerical Simulation of Flow Filed in ESP Outlet with Moving Electrode Type

The numerical simulation of 2-D flow filed in ESP with Moving Electrode Type was carried out, in which a 2-equation model was adopted to simulate the flow field and the computation based on the SIMPLE algorithm and the geometric model was meshed with GAMBIT. The numerical simulation of flow field with FLUENT came to the conclusion that the air flow distribution in the electro static precipitator will change when the opening ratio of the electrodes and the air flow velocity in operation have changed, so the result of numerical simulation was reasonable for the design and operation of the ESP with Moving Electrode Type.
