Drag forces under longitudinal interaction of two particles

الملخص EN

Direct measurements of drag force on two interacting particles arranged in the longitudinal direction for particle ? numbers varying from 10 to are conducted using a micro-force measurement system.

The effect of the interparticle distance and Reynolds number on the drag forces is examined.

An empirical equation is obtained to dacribe the effect of the interparticle distance (l / d) on the dimensionless drag.
