Abstract In most industries to remove gas–solid particle separation, cyclone separators are used. Though it plays a major role, the efficiency of the cyclone is not up to mark. In order to fulfil that with the help of CFD platform to investigate the flow field in Stairmand cyclone. For a numerical analysis 3D, grid independent Stairmand cyclone is performed by a Eulerian–Lagrangian model with Reynolds stress model (RSM) is chosen as a turbulence closure model and also grid convergence index study has been carried out. The numerical analysis is carried out with the coupled flow pressure field and two-way coupled particle tracking (stochastic tracking model) which were verified with experimental data. In Stairmand cyclone, the performance is affected by the collision between the circulating gas stream and the gas stream of fresh inlet charge at the junction of inlet duct results in flow short-circuiting (pressure drop). To avoid short-circuiting, spiral inlet is designed for cyclone separator and also study has been extended out numerically for the spiral cyclone separator (SCS) with different vortex finder diameter, length, eccentric position, convergent and divergent type vortex finder.
