N. Toosi University of Technology Majid Bazargan Journal Article 2022 07 31 The main objective of the current numerical research is to study the effects of covering the impingement surface by a porous layer in order to increase the heat uniformity throughout the surface without losing the advantage of high heat transfer rates in a multiple impinging jet flow. The porosity, permeability and thickness of the porous layer are considered. The results show that among the scenarios studied, the highest overall heat transfer performance coefficient is equal to 23.45 and corresponds to the case where the porous layer covers half of the depth of the channel and the porosity and permeability of the porous medium are at their highest (ԑ=0.8) and lowest (k=1.76*10^-12) values, respectively. This study shows that using different arrangement for porous media can lead to a more uniform heat generation rate while maintaining high heat transfer in the flow of multiple impinging jets..
