An Efficient Numerical Method for Pressure Loss Investigation in an Oil/Air Separator with Metal Foam in an Aero-Engine

Energies, 2020
An efficient method of simulating pressure loss in a separator with metal foam is reported. In this method, a metal foam is modeled as a porous media having homogenized permeability and inertial resistance coefficients.

Thermal-Hydraulic Performance of Metal Foam Heat Exchangers [PDF]

, 2012
Due to their large surface-area-to-volume ratio and tortuous structure, metal foams hold promise for heat transfer applications. Both of these factors increase the heat transfer by enhancing the mixing and surface area.

A further discussion on the effective thermal conductivity of metal foam: An improved model [PDF]

, 2015
In this study, we explain the causes and effects of the geometrical impossible result encountered in the widely adopted tetrakaidecahedron model (Boomsma and Poulikakos, 2001; Dai et al., 2010) for the effective thermal conductivities (ETCs) of metal ...
