Related referential studies of the temperature influence on hydrodynamics ingas-solid fluidized beds were reviewed. Two-dimensional (2-D) numerical modeling andsimulation based on a two-fluid model for gas-solid fluidization was conducted. The modified IMF algorithm was employed to solve the governing equations expressed in the conservative form in the 2-D Cartesian/Cylindrical coordinates. The solid-phase pressurewas modeled via the local sound speed.
