News ESI Group is pleased to announce the release of the 2006 version of CFD-CADalyzer. CFD-CADalyzer is the perfect tool for both CAD engineers and CFD analysts to perform design level analysis with a simple and intuitive interface. CFD-CADalyzer, a complete package in itself with built-in pre and post-processor, enables the simulation of flow and heat transfer, and allows the comparison of results over a range of varying geometries and operational conditions.

In pre-processing, specifically mesh building, mesh quality is very important in setting up a complex geometry problem. Now with CFD-CADalyzer 2006 significantly better mesh quality is obtained through suppression of tiny features coupled with intelligent boundary layer meshing.

Modeling Metal Foam Heat Exchanger
Posted Fri February 17, 2006 @09:13AM
Print version Email story Tweet story
Help Desk David Dunavant writes "I am wondering if my modeling approach is correct. I have modified thermal conductivity, k, and specific heat, cp, of my fluid based on volume ratios and corresponding properties of metal foam and fluid.

Volumetric flow rate of the fluid is constant. It seems like different pressure drops from different pressure-velocity curves corresponding to different pores per inch (PPI) will not affect thermal performance.

Heat exchange of metal foam is about twice that of conventional baffle-type design. Furthermore pressure drop can be greatly reduced.

Also would appreciate if anyone can provide information about permeability, K, and inertia coefficient, C, of aluminum metal foam since suppliers won't release much information although I do have limited data.

Any assistance is appreciated, thanks.
David Dunavant"
