Calculation Method of the Frictional Pressure Drop for Sintered Fibrous Porous Pipes with Permeability and Friction Factor

Abstract

The characteristics of the frictional pressure drop on the in-pipe flow filled with a sintered fibrous porous body were investigated by experimental study. In this study, the pipe friction coefficient, and Reynolds number were derived by using the shape coefficient and permeability for the sintered fibrous porous body. The porosity, inner diameter, average fiber diameter, and porous body filling length were parameters. The calculation method of the frictional pressure drop was proposed on this study, considers the flow velocity in the pipe that changes depending on the porosity, and the frictional pressure drop can be calculated within a range error of 12.3% at the maximum, and an average of 5.1%.
