Numerical simulation and experimental study of gas
Therefore, with the increase of gas velocity, the separation efficiency of dust increased first and then decreased. The forces on particles in the flow field were complex, including centrifugal force, Magnus force, fluid medium resistance, additional mass force, pressure gradient force, Bassett force and the force generated by particle collision.

Dehydration by coupling centrifuge drainage with microwave drying
During centrifugal drainage, if rotational speed is instantaneously set to zero, liquid distribution in the cake will occur. It is possible to investigate the kinetics of this effect with the numerical model. As shown in Fig. 4, liquid pushed on filter media by centrifugal force redistributes as soon as basket rotation is stopped.
