Consider a small rigid spherical particle of radius a, fully immersed in a viscous incompressible Newtonian fluid of shear viscosity η above a hard-wall with stick (no-slip) boundary conditions, located at the plane z = 0. A constant positive (external) torque Tx is applied on the particle.
My question is:
Assuming low Reynolds number hydrodynamics, the particle will move along the y direction due to hydrodynamic interactions. But, does the velocity along y have a positive or negative sign?
Any help would be highly appreciated.
Thank you
Eric
