Keywords: CFD, cyclone spray scrubber, flow pattern, velocity, turbulent intensity Abstract.
The numerical simulation of the fluid flow is presented by CFD technique to characterize the flow pattern of cyclone spray scrubber.
In this work, the numerical simulations of the gas flow pattern in the cyclone spray scrubber including the tangential velocity, axial velocity and turbulent intensity, are performed and compared by the CFD software package to reveal the effect of cyclonic flow on the absorbing enhancement.
Although numerical simulation is relatively complex and demands much computational time, due to the nature of the gas turbulence model and the particle track method for its implementation, it does appear to demonstrate that the CFD technique can be successfully applied to strongly swirling turbulent gas flows.
