Summary

Abstract: An experimental investigation was conducted to obtain information on air-flow uniformity and pressure-level effects for various meshes of stainless-steel corduroy wire cloth, and permeability and strength data for a 20- by 20-mesh stainless-steel wire cloth. It was found that close control of the wire cloth thickness yielded sufficiently uniform air flow and that available methods may be used to predict the effect of pressure level. Permeability and strengths of the 20- by 20-mesh wire cloth were similar to those already available from other meshes. The reduced tensile strength of the 20- by 20-mesh wire cloth in the direction of the primary stresses is one and a half to three times as great as the strength of the best porous sintered materials presently available.
