• An experimental study of heat transfer has been conducted in a channel flow with a rectangular cylinder having various width-to-hight ratios, b / h, of 0.5, 1, 2 and 3. Time-averaged heat transfer coefficients and the fluctuations of wall heat flux have been measured. Heat transfer is augmented extensively at the downstream region of the cylinder. In order to examine the relationship between the heat transfer enhancement and the shedding vortices from the cylinder, flow visualization by a smoke-wire method using a high-speed video recording system has been carried out simultaneously with wall heat flux measurement. It is clarified that the heat transfer is augmented by the wall-ward flow induced by the clockwise and counterclockwise vortices shed alternately from the cylinder.
