dc.description.abstractThe present study is focused on investigation of heat transfer from a porous plate by cooling of air and surfacewith transpiration cooling. Effects of Reynolds number of hot air (Re= 3035, 3200, 3300, 3580), effects of flowrate of water as a coolant (? water = 0.000083, 0.000116, 0.000166, 0.000249 kg/s) on local wall temperature andcooling efficiency of porous flat and the system inside a rectangular channel with air as a hot gas stream andwater as a coolant were investigated numerically. In this study; different from the literature, transpiration coolingwas used as a cooling mechanism of air. It was observed from the results that increasing Reynolds numbercauses an increase on surface temperature and a decrease on cooling efficiency of porous plate and system.Increase of Reynolds number from Re=3035 to 9430 causes a decrease of efficiency of the system of 13.7%.Increasing water flow rate nine times causes not only a decrease on average surface temperature of 1.1% but alsoan increase of 6.5% on efficiency of porous plate and an increase of 19.1% on cooling efficiency of the system.Numerical results prepared by RNG k-? turbulence model generally have a good approximation withexperimental results.
