Numerical simulation of particle plume resident time affected by horizontal crosswise wind speed

This article explores the resident time of free-falling particle plume with the characteristics of gas-solid two-phase flow affected by horizontal crosswise wind speed. The computational fluid dynamic software FLUENT was adopted in this study. The numerical simulation was carried out to study the influence of horizontal environmental wind speed to the velocity of particle plume. In the simulation, the ambient wind speeds were assumed as 1, 1.2, 1.4, 1.6, and 1.8 m/s. The particle diameter was set as 567 μm and the mass flow was given as 5.2 g/s. The Euler and Lagrangian models were used to calculate the coupling pressure and velocities of the particles and the entrained air in the simulation. The simulation results showed that the greater the horizontal wind speed was the shorter the particle resident time and the shorter the time of particle velocity reached the maximum value.
