Inertia and interception in the deposition of particles from boundary layers

Abstract

The treatment of Parnas and Friedlander for the problem of particle capture by interception in laminar boundary layers is generalized to include the effect of inertia. For a circular cylinder in cross-flow it is seen that the collection efficiency is initially reduced by inertia at small Stokes number, Stk, and depends mainly on the product of Stk and the square root of the Reynolds number. An approximate method of extending this work to other two-dimensional or axisymmetric geometries is sketched. © 1986 Elsevier Science Publishing Co., Inc.
