Experimental study of hydraulic resistance in heat exchangers with interchannel coolant transpiration

摘要

The results of experimental study of hydraulic resistance of packs of wire gauze filter meshes II24, II60, C120, C200, C600/2200 with intermesh and orthogonal gas filtration to mesh surface are presented. The experimental data on coefficients of hydraulic resistance of porous mesh materials, produced by a diffusion vacuum welding of wire gauze meshes of stainless steel, nickel, invar and copper is obtained. It is determined that the hydraulic resistance of porous mesh materials is affected not only by a porosity, but a type and number of mesh, direction of gas filtration, presence of porous mesh materials machining. Hydraulic resistance of a copper high-porous cell material was studied.
