Forced Convection Across Horizontal Hot Cylinder Using Slotted Deflector Plate
Abstract According to Kirchoff–Helmhotlz solution for flow across a horizontal cylinder, the boundary layer separates at an angle of 55° from horizontal plane, so due to this separation phenomenon of boundary layer, the heat transfers from the upper side of a hot cylinder is minimum. Heat transfer from upper side can be increased by preventing the separation of boundary layer. Here we delay the separation of boundary layer by using a slotted deflector plate. Due to this accelerated air passes over upper side of the cylinder. The optimum distance at which the plate is to be kept from the cylinder is found out through this experiment. This experiment is also carried out by varying the width of the slot, the heat input to the cylinder and the velocity of flow of the air. We find that this method is more effective at higher temperatures and the highest temperature difference achieved was 20 % which is significant for cooing industrial equipments.
