Abstract:
The present study analysis the effect of particles diameter on pressure drop in a particle-laden horizontal channel flow. Equations of fluid motion are considered as a continuous phase and particles as a discrete phase, and the Eulerian-Lagrangian approach or discrete phase model (DPM) in the software package FLUENT is employed to simulate. The continuous gas flow is predicted by solving Navier–Stokes equations using a standard k–ɛ turbulence model and velocity and pressure fields are achieved. The fate of each particle is determined by integration on the equation of motion of particles. In this study used the two-way coupling to impose the effect of particles on the continuous phase. The predicted fluid and particle mean velocity are in good agreement with the available experimental data by Tsuji et al. (1987) involves large particles with mean diameter 1mm and mass loading ratio up to 3(kg/kg). finally, observed that the pressure drop increases in the channel by decreasing the particles diameter.
