Natural Convection Above A Horizontal Heat Source

Abstract

An investigation of natural convection heat transfer from a flush mounted heater on a larger horizontal substrate in water has been conducted. The focus of the present investigation was on the buoyant flow above the heat source. Temperature measurements in the buoyant plume were made at various locations and heights, for a number of input powers using a traversing thermocouple probe. Simple signal processing was performed on the temperature measurements to attempt to investigate the reported meandering motions in the plume and the transition from laminar to turbulent buoyant flow. These measurements are interpreted based on flow visualizations.
