Abstract
Simulation using computational fluid dynamic techniques were performed intending to analyse the flow characteristic inside a cyclone separator in four different inlet velocities, 7ms−1 , 13𝑚𝑠 −1 , 16𝑚𝑠 −1 , 𝑎𝑛𝑑 22𝑚𝑠 −1 . The experimental data used in validation of simulations were obtained from the literature. Ideal y + is controlled with the calculation of first layer thickness and grids verification is done. K-epsilon RNG and Reynolds Stress Models are used to simulate the model. Flow characteristic study is done in transient state with a developed robust numerical model. Profiles and contours show velocity magnitude vector, vorticity, static pressure, turbulent kinetic energy, and RMS of turbulent velocity fluctuation. RSM model is used results in less discrepancy in term of static pressure drop. The air flow inside the cyclone separator is highly turbulent and air flow behaviour is clearly observed.
