چکیده:

The present study analysis the effect of mass loading ratio and nano-particles diameter on pressure drop in a Gas-Particle horizontal channel flow. Equations of fluid motion are considered as a continuous phase and nano-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. The fate of each nano-particle is determined by integration on the equation of motion of nano-particles. In this study used the two-way coupling to impose the effect of nano-particles on the continuous phase. The predicted fluid and particles 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, by decreasing particle diameter up to 10nm, observed that the pressure drop increases in the channel by increasing the mass loading ratio and decreasing particle diameter
