A COOPERATIVE PROGRAM OF FUNDAMENTAL RESEARCH AS RELATED TO JET PROPULSION ON LAMINAR FLOW THROUGH A CHANNEL OR TUBE WITH POROUS WALLS:APPLICATION OF METHOD OF AVERAGES

摘要

The purpose of this paper is to present a simple approximate closed-form solution for the flow through a channel and through a circular tube with porous walls valid for the entire range of normal fluid injection velocities from zero to indefinitely large. The method of analysis based on the method of averages.
