Microscopic Fluid Dynamic Simulation of the Metal Foam Using Idealized Cell Structure

Abstract

Simple, yet accurate representation of cell structure is essential when conducting a multidimensional thermo-fluid simulation on porous medium in microscopic scale. Presented in this paper is a study of the fluid dynamic simulation of the nickel metal foam's unit cell domain using idealized cell structure. Commercially available multi-physics package, COMSOL, was utilized to conduct numerical simulation. Simplified methodology to create an idealized cell structure of metal foam is presented, and simulation results on pressure drop are discussed. Nonlinear solver in COMSOL was utilized to solve the unidirectional pressure drop and permeability across the cell structure. Obtained results showed confirmed agreement to the data obtained from the experiment and previous researchers, verifying the practicality and applicability of the proposed unit cell structure.
