The Solution to a Nonlinear Lamm Equation in the Faxén Approximation.

Abstract

An exact solution in the Faxén approximation is given for the Lamm equation in which the sedimentation coefficient is related to concentration as s = s0(1-kc). It is shown that the solution in this case can be expressed in terms of the solution to the linear case (k =0) with a modified argument. The boundary sharpening phenomenon expresses itself very clearly in the solution presented here.
