Abstract
Natural convection heat transfer from a flush mounted heater on a larger horizontal substrate in water has been investigated for both steady and periodic input powers. For steady power conditions, the heat flux was varied from 222 to 6800 W/m(2). Heater surface temperatures were measured at several locations in order to develop a non-dimensional heat transfer correlation. Three types of periodic input powers were tested: a triangular wave, an approximate square wave, a sinusoidal wave. Mean, amplitude, and frequency were varied for each wave. Temperature measurements at selected heater locations were compared with steady state conditions to determine how heat transfer enhancement.
