Thermal transport analysis in parallel-plate channel filled with open-celled metallic foams

Flow and heat transfer characteristics of nanofluid flowing through metal foams

“…Open-celled metal foam is a kind of materials with sufficiently-large surface area density (500-7500 m 2 m À3 [7]) and it is usually sintered on the solid-wall. Additionally, it owns other thermal advantages, such as high solid thermal conductivity, strong flow-mixing capability, high porosity and low-density, which makes it useful in compact heat exchangers and heat sinks, chemical reformers, solar collectors, and efficient combustor [7][8][9].…”

“…For flow in metal foams, Darcy model, Brinkman model or Forchheimer model may be used for specific velocity range and viscous effect of impermeable wall [8]. For heat transfer in metal foams, the local thermal equilibrium (LTE) model or the local thermal non-equilibrium (LTNE) model may be used in principle.…”

Effects of key factors on solar aided methane steam reforming in porous medium thermochemical reactor

“…The LTNE model with P1 approximation is used to investigate the temperature distributions which can provide more temperature information [26][27][28][29]. The influences of radiative heat loss and thermal conductivity of porous matrix on temperature distribution and thermochemical reaction are numerically studied.…”

A model on the basis of analytics for computing maximum heat transfer in porous fins

“…Makinde and Aziz [43] used a numerical approach to study the heat and mass transfer from a vertical plate embedded in a porous medium. Recently Xu et al [44] analyzed the thermal transport in highly porous, opencelled metallic foams sandwiched between two infinite parallel plates using the Brinkman-Darcy and two-equation models. They highlighted that the comprehensive performance of a metallic foam channel is superior to empty channel in a particular porosity range and optimal pore density range.…”
