Computational Fluid Dynamic- Two Fluid Model Study of Gas-Solid Heat Transfer in a Riser with Various Inclination Angles
A two fluid model (TFM) was used to study gas-solid heat transfer in a riser with different inclination angles. A two dimensional pipe with 5.8 cm internal diameter and 5 meter length was chosen. Effect of bed angle and solid particles feed rate were studied on the heat transfer behavior of gas and solid particles. Obtained results from simulation are compared with the experimental data in the...

متن کاملUtilising Computational Fluid Dynamics (CFD) for the Modelling of Granular Material in Large-Scale Engineering Processes
In this paper, the framework is described for the modelling of granular material by employing Computational Fluid Dynamics (CFD). This is achieved through the use and implementation in the continuum theory of constitutive relations, which are derived in a granular dynamics framework and parametrise particle interactions that occur at the micro-scale level. The simulation of a process often met ...
متن کاملGas-Liquid-Solid Fluidized Bed Simulation by Computational Fluid Dynamics
Gas-liquid-solid fluidized bed technique has emerged recently as one of the most promising one for three phase operations involved in chemical, biochemical, petrochemical, pharmaceutical processing industries. Out of the fundamental characteristics of a three-phase fluidized bed, the gas hold up and liquid hold up behaviours have been studied extensively. Considering the various researchers’ fi...
