Analysis of film condensation on a vertical plate embedded in porous media under local thermal non-equilibrium condition

Case Studies in Thermal Engineering
Film condensation on a vertical plate embedded in porous media under the local thermal non-equilibrium (LTNE) condition is analyzed. The Darcy-Brinkman model and the LTNE model are introduced to establish the mathematical formulation.

Flow and Convection in Metal Foams: A Survey and New CFD Results

Fluids, 2020
Metal foams are widely studied as possible tools for the enhancement of heat transfer from hot bodies. The basic idea is that a metal foam tends to significantly increase the heat exchange area between the hot solid body and the external cooling fluid ...

New Criteria to Estimate Local Thermal Nonequilibrium Conditions for Heat Transport in Porous Aquifers

Water Resources Research, Volume 60, Issue 7, July 2024.
Abstract A fundamental assumption in numerous studies of heat transfer in porous media is local thermal equilibrium (LTE), which assumes that the temperature of the porous media at the fluid and solid interface is in instantaneous equilibrium. Although significant efforts have been made to quantify the occurrence and consequences of local thermal ...

Heat transfer characteristics of water flow through a single rock fracture: The combined effects of shear and surface roughness

Energy Science &Engineering, Volume 12, Issue 3, Page 561-576, March 2024.
A systematic numerical simulation based on the double‐rough‐walled fracture model has been presented to clarify the fluid flow and heat transfer characteristics of fractures under shear stress in high‐temperature rock environments. A series of geologically realistic fracture models were established using a modified successive random additions algorithm.
