A ANALYSIS OF HEAT TRANSFER ENHANCEMENT IN PULSATING TURBULENT FLOW IN A PIPE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 7
Abstract
Enhancement of heat transfer in a tube is a remarkable engineering achievement as it has the potential to reduce power consumptions of industrial heat exchangers significantly. Consequently, the power demand of industry would be reduced; lowering the need for excessive amounts of power and decreasing harmful emissions to the environment by power generators The enhancement and determination of pipe wall convective heat transfer characteristics has likely been one of the most interesting engineering aspects of heat transfer research. Different methods to enhance the heat transfer coefficient were developed. Thinking of such notion, one such technique that has been widely used in industry is the use of flow pulsation in the tube. Pulsating flows can be produced by reciprocating pump or by steady flow pump together with some mechanical pulsating devices. It may normally be expected that the heat transfer to or from the flow would be changed since the pulsation would alter the thickness of the boundary layer and hence the thermal resistance. In this paper effect of pulsation on heat transfer is studied and it is find out that pulsation does have positive influence on the heat transfer.
