Effect of Mass Loading Ratio on Pressure Drop in a Particle-Laden Horizontal Channel Flow

The present study analysis the effect of mass loading ratio on pressure drop in a particle-laden horizontalchannel 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 isemployed to simulate. The continuous gas flow is predicted by solving Navier–Stokes equations using astandard k–ɛ turbulence model and velocity and pressure fields are achieved. The fate of each particle isdetermined by integration on the equation of motion of particles. In this study used the two-way coupling toimpose the effect of particles on the continuous phase. The predicted fluid and particle mean velocity are ingood agreement with the available experimental data by Tsuji et al. (1987) involves large particles with meandiameter 1mm and mass loading ratio up to 3(kg/kg). finally, observed that the pressure drop increases in thechannel by increasing the mass loading ratio.
