Heat Transfer Enhancement using Nozzle Inserts in a Pipe Flow
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 4
Abstract
The Conventional sources of energy have been depleting at a high rate, which makes future sustainable development of energy use very difficult. Thus, researches on seeking ways to reduce the size and cost of heat exchangers have been conducted. Size and cost can be reduced by increasing the heat transfer coefficient. The increase in heat transfer coefficient can be done by many methods the common method is by Enhancement process. In this process enhancement device such as nozzles, twisted tapes etc are used for enhancing the heat transfer coefficient. In the present paper the work nozzles are used as enhancement device and Convective heat transfer in a tube is dynamically different from one without inserts. The main concept is due to insertion of nozzles in to the plain pipe and swirl motion is created and contact area decreases thereby increasing the heat transfer coefficient 'h', in the tube flow, an experimental setup is prepared and experiments are conducted by using water as a medium and results are determined. The experiments are carried for the plain pipe without any inserts at different heat input and different mass flow rates and corresponding heat transfer coefficient are calculated for each case, in the same way experiments are carried out with nozzle inserts at different heat input and different mass flow rates and corresponding heat transfer coefficient are calculated for each case. Thus, by these enhancement techniques, heat transfer rate is determined. R. Rudrabhi Ramu | P. H. J. Venkatesh | K.
