INVESTIGATION OF INLET VELOCITY EFFECT ON HIGH EFFICIENCY SWIFT CYCLONE
Abstract
In this paper, study is performed in order to demonstrate the effect of the inlet velocity on collection efficiency and pressure drop by using numerical methods. Numerical simulation is accomplished for six different inlet velocity at range of 10-20 m/s. Gridding was done with small elements to obtain better results. Turbulent flow is analyzed using Reynolds Stress Model (RSM). Set appropriate time steps to model the transient processes is 1000 for 5 ms with 10000 iterations. Rosin-Ramler size distribution method was used to calculate particle mass fraction. Centrifugal force increased because that for value of inlet velocity increases, the tangential velocity enhances. Based on this situation, it can be concluded that for the particles to move towards the cyclone wall and the collection efficiency increased. It is seen that with the increase in inlet velocity, the pressure drop increases greatly due to the increase in the rotating flow. It is expressed that this change increases as exponentially. It is also observed pressure on cyclone wall markedly increased with the increase inlet velocity.
