What Is the Expression for Settling Velocity in a Rotating Field?

In summary, the expression for settling velocity in a rotating field considers the effects of centrifugal and Coriolis forces on particles in a fluid. The settling velocity is influenced by factors such as particle size, shape, and density, as well as fluid properties like viscosity and density. The equation typically incorporates terms that account for the rotation rate of the field, leading to variations in the effective gravitational force experienced by the particles, thereby altering their settling behavior compared to non-rotating conditions.

TL;DR Summary
Hi there, The settling velocity is terminal velocity at which drag force is equal to the gravity. When the sphere is in rotating field the terminal settling velocity is reduced. What will be the expression for it in rotating field?
