Heat transfer in a channel of rough wall is simulated in this work. Two kinds of roughness are considered, i.e., one assumes sandgrain roughness based on roughness model and the other regularly arranged two-dimensional ribs. No models other than sand-grain roughness implemented in the simulation. Fo
## Abstract Experiments have been performed for turbulent channel flow obstructed with a flat body. The local heat transfer coefficient and the wall static pressure were measured on two kinds of flat bodies for which the trailing edge shape differed. The length of the body, the thickness of the bod
