Abstract
The purpose of this report is to present experimental data that demonstrate the relationship between air velocity and surface temperature for a cylinder subjected to forced convection. This experiment will also determine the effects of forced convection on heat transfer from the surface of a cylinder at varying air velocities and surface temperatures. The forced convection theory is based on the same principle of moving air over a surface to increase the heat transfer rate from a surface. Therefore a surface subjected to forced convection will have a lower surface temperature than the same surface subjected to free convection, for the same power input. The force convection will be provided by the air compressor on the apparatus. The heat transfer will also be accomplished by means of radiation heat transfer as heat will be absorbed by the surroundings.
The experiment is setup using (see figure1): • HT10X Heat Transfer
