文摘
- •
The relative importance of interphase forces obtained by theoretical analysis agrees well with that calculated by numerical simulation.
- •
Integral time scale for Basset force should be no smaller than the particle relaxation time.
- •
Basset force and lift force are important relative to the drag force.
- •
Particle transverse motion is confirmed to be the main reason for flatter particle velocity profile.
