“…To measure in-plane intrinsic permeability of meshes, researchers have developed methods considering stacks of meshes submerged in a liquid to understand how different characteristics of the mesh, such as the number of layers, wire diameter and spacing, crimping factor, mesh thickness, and stacking density, can influence single-phase flow through the mesh. [23][24][25][26][27][28][29][30] The results of these studies have contributed to the development of models, such as the modified Blake-Kozeny equation, which can predict the intrinsic permeability of metal meshes for certain configurations. However, both the measurement methods and mathematical models may not be accurate for very thin stacks of mesh and do not address meshes with free surfaces.…”

The permeability of mesh wicks is important for various applications, including two‐phase heat transfer. However, the understanding of the permeability of single‐layer, free‐standing mesh wicks, with liquid–gas interfaces on both sides, is limited. A novel and simpler method is presented to determine the permeability of a free‐standing wick and apply it to a representative mesh. This method involves modifying the capillary pressure via elevation and simultaneously measuring the permeability to determine the permeability‐capillary pressure relationship. When applied to a copper mesh with plain weave having undergone surface cleaning, the permeability is found to decrease as capillary pressure for deionized water increases. A dimensional analysis is presented to generalize this data for other mesh sizes with similar weaves and fluids. The behavior of mesh in application is modeled, based on the integration of Darcy's law with an analytic function fit to measured data, and parametric studies are conducted to investigate the superficial velocity of liquids through the mesh under varying driving pressures, transport lengths, and liquid viscosity, based on the obtained capillary pressure–permeability relationship. This study provides valuable insights into the transport properties of mesh wicks, with potential applications in fields such as electronics cooling, electrochemical devices, and fluid purification technologies.

The permeability of mesh wicks is important for various applications, for example two-phase heat transfer. However, our understanding of the permeability of single-layer, free-standing mesh wicks (SLFSMW), with liquid-gas interfaces on both sides, is limited. We present a novel and simpler method to determine the permeability of a SLFSMW and apply it to a representative mesh. Our method involves modifying the capillary pressures elevation and simultaneously measuring the permeability to determine the permeability-capillary pressure relationship. When applied to a copper mesh with plain weave having undergone careful surface cleaning, the permeability is found to decrease as capillary pressure for deionized (DI) water increases. We present dimensional analysis to generalize our data for other mesh sizes with similar weaves, and fluids. We model the behavior of mesh in application based on the integration of Darcy’s law with an analytic function fit to measured data and conduct parametric studies to investigate the superficial velocity of liquids through the mesh under varying driving pressures, transport lengths, and liquid viscosity based on the obtained capillary pressure-permeability relationship. This study provides valuable insights into the transport properties of mesh wicks, with potential applications in fields such as electronics cooling, electrochemical devices, and fluid purification technologies.
