We give a general formulation of handling the Brownian motion of a rigid particle of arbitrary shape ina Newtonian fluid subject to external force,torque and velocity field.We show how to include the effectof the Brownian motion in Langevin equation and in Smoluchowskii equation.As an example,we discuss the effect of the translation–rotation coupling on theBrownian motion of free particle,and the separation of chiral particles in shear and electric field.
