Matrix Cooling Configuration: A Computational Study
This paper describes 3D numerical simulation of matrix cooling configuration having two and three layered
Rectangular sub-channels. The computational study has been conducted over the Reynolds number range of 24000-60000.
The Nusselt number, friction factor and overall thermal performance have been evaluated and compared with smooth
channel. The present work shows the enhancement in heat transfer of matrix configuration and this is due to increased heat
transfer area, impinging and swirling flow in the sub-channels. The Nusselt number ratios (Nu/Nu0) for the whole matrix
structure under stationary conditions are approximately 4-5 times higher than those of smooth channel.
