Numerical Analysis of Air Flow through Metal Foams

Open Cell Metal Foams: Measurement and Numerical Modelling of Fluid Flow and Heat Transfer

We herein present results from experimental investigations and new numerical methods for the investigation of fluid flow and heat transfer in cellular solids, in particular open cell metal foams. Results from a custom made test facility contribute to enlarge the public available database of open cell metal foams and serve for the validation of applied commercial and inhouse numerical methods. C...

Numerical Simulation of Turbulent Subsonic Compressible Flow through Rectangular Microchannel

In this study, turbulent compressible gas flow in a rectangular micro-channel is numerically investigated. The gas flow assumed to be in the subsonic regime up to Mach number about 0.7. Five low and high Reynolds number RANS turbulence models are used for modeling the turbulent flow. Two types of mesh are generated depending on the employed turbulence model. The computations are performed for R...

Numerical Study of Non-Newtonian Flow Through Rectangular Microchannels

A numerical investigation was carried out to solve the flow dimensionless partial differential equations through rectangular microchannels. A purely viscous power law <span style="font-size: 10pt; colo...

Microtomography-Based Simulation of Transport Through Open-Cell Metal Foams

Amorphous metal foams

As recently demonstrated, amorphous metal foams are highly ductile in compression, and thus offer attractive compromises in mechanical and physical properties between crystalline metallic and ceramic foams. Challenges associated with fabrication of amorphous metal foams are critically assessed in the context of current and future processing methods, and conclusions are drawn regarding the prope...
