The present work deals with the computation of the gas-solid two-phase flow pressure drop across thin and thick orifices for a vertically downward flow configuration at the higher limits of a dilute phase flow situation(0.01≤αs,in≤0.10).The Eulerian-Eulerian(two-fluid)model has been used in conjunction with the kinetic theory of granular flow with a four-way coupling *** validation of the solution process has been performed by comparing the computational result with the existing experimental *** is observed that the two-phase flow pressure drop across the orifice increases with an increase in the thickness of the orifice,and the effect is more prominent at higher solid *** pressure drop is found to increase with an increase in the solid volume *** increase in the Reynolds number or the area ratio increases the pressure *** increase in the size of the particles reduces the pressure drop across the orifice at both small and relatively large solid volume ***,a two-phase multiplier has been proposed in terms of the relevant parameters,which can be useful to evaluate the gas-solid two-phase flow pressure drop across the orifice and can subsequently help to improve the system performance.
