THE STUDY OF THE EFFECTS OF RADIATION AND BLOWING FROM THE WALL OF A VERTICAL CHANNEL ON THE TURBULENT FREE CONVECTION HEAT TRANSFER Ali Yari1 , Siamak Hosseinzadeh2* , Amin Bahrami3 , Morteza Radmanesh4 1 Department of Mechanical Engineering, University of Shiraz, Shiraz, Iran 2* Department of Mechanical Engineering, Islamic Azad University, West Tehran Branch, Tehran, Iran 3Department of Mechanical Engineering, University of Science and Technology, Tehran, Iran 4Department of Mechanical Engineering, University College of Rouzbahan, Sari, Iran ABSTRACT This article investigates the effects of radiation and blowing from a wall on a turbulent heat transfer in vertical channels with asymmetrical heating. The equations involved were numerically solved with three turbulent models including Spalart Allmaras, R-N-G k-ε with "Standard Wall Function" wall nearby model, R-N-G k-ε with "Enhanced Wall Treatment" wall nearby model and "Ray Tracing" rad...
