Webb22 juli 2024 · This work analyzes the porosity effects on laminar flow and drag reduction of Newtonian fluids flowing over and through permeable surfaces. A fully developed laminar flow in a channel partially replaced with a porous material is considered. The analytical solutions for the velocity and shear stress are given and examined to identify … Webb1 dec. 1989 · The Chemical Engineering Journal, 42 (1989) 193 - 204 193 Laminar Flow in Channels with Porous Walls JOCELYNE GRANGER, JOHN DODDS and NOEL MIDOUX Laboratoire des Sciences du Genie Chimique, CNRS-ENSIC, 1 rue Grandville, 54042 Nancy (France) (Received November 4, 1988; in final form May 22, 1989) …
Laminar Flow in a Uniformly Porous Channel - Cambridge Core
WebbThe effect of injection and suction at the wall on the two-dimensional steady-state laminar flow of a fluid in a porous-wall pipe has been investigated in detail by the solution of the Navier-Stokes equations in cylindrical co-ordinates.

Webb1 dec. 2024 · Langmuir : the ACS journal of surfaces and colloids. 2024. TLDR. This work shows how cylindrical liquid-in-liquid flow leads to drag reduction of 60-99% for sub-mm and mm-sized channels, regardless of whether the viscosity of the transported liquid is larger or smaller than that of the confining one. 1. Webb6 sep. 2024 · Aluminum porous foams are used in the present study. Four impinging jet configurations are considered: jet impingement (1) without porous media, (2) over the porous heat sink, (3) with porous obstacle case, and (4) through porous passage. the plan is coming together meme
