“…The capillary action of the wick can increase the heat transfer coefficient and the critical heat flux in evaporation and boiling heat transfer processes through optimal delivery of coolant fluid to the heated area. [10][11][12][13] The permeability of a mesh wick refers to its ability to allow fluids to pass through it. It is influenced by the size and shape of the pores in the wick, and when multiple, immiscible phases are present, the surface tension of the liquids and surface energy of the matrix and the relative pressure within each phase.…”

“…Additional studies have measured in-plane relative permeability of thin, porous films. [13,32] The environment can play a role in the fluid flow properties of woven meshes, particularly through its effect on evaporation from the wick. [33] Changes in temperature and relative humidity can alter the radius of curvature of the liquid-vapor interface as described by the Kelvin equation.…”

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.
