Understanding and accurately modeling the behavior of two-phase flows in these devices are critical for optimizing their performance and efficiency. The cut cell technique is employed, providing a flexible and efficient means of representing intricate geometries within axisymmetric domains. The paper discusses the governing equations, numerical discretization schemes, and boundary conditions used in the Eulerian-Eulerian approach with the cut cell technique for axisymmetric diffusers. Various aspects of the two-phase gas-solid flow, including particle-particle and particle-wall interactions, interphase momentum transfer, and phase segregation, are investigated. The governing equations are solved using house developed code called FORTRAN, a widely used programming language in scientific and engineering simulations. The results of this study will provide valuable insights into the behavior of gas-solid two-phase flows in axisymmetric diffuser. A parametric study of the impact of particles diameters (100, 200,300 \(\mu m\) ), the solid volume loading ratios \((0.005, 0.008, 0.01)\) and cant angle (4.5°, 7°, 9.5°) effect of axisymmetric diffuser on the local skin friction, pressure, velocity, turbulent kinetic energy, and separation zone.
