5th International Conference on Porous Media and Their Applications in Science, Engineering and Industry
This paper presents the experimental analysis of air flow vortex propagation through porous screens. This study is conducted by a new and unique experimental setup for ve- locity measurements and visualization of air vortex interac- tion with porous screen. A custom-made, high-precision vortex generator provides a variety of velocity profiles for vortex generation with an unprecedented level of precision. The flow fields are captured with the use of a fog gener- ator and a high-speed CCD camera. The porous screens are constructed out of acrylic rods with various orientations, thickness, and porosities from rod separation. The results presented in this …

Multilayer Minichannel Heat Sinks: The Effect Of Porosity Scaling On Pressure Drop, Arun K. Karunanithi,, Fatemeh Hassanipour

Previous studies have shown that stacked multi-layer mini-channels heat sinks with square or circular channels have advantages over traditional single layered channels in terms of both pressure drop and thermal resistance. In this work, porous media is used in the multi-layered stacked mini-channels instead of square or rectangular channels and the effect of the same on pressure drop and thermal perfor- mance is studied. Porosity scaling is done between the lay- ers of porous media and is compared with unscaled stacked multilayer channel. Porosity scaling allows the porosity to vary from one layer to the next layer and could result …
