Numerical Investigation of Heat Transfer Augmentation for Flow through Tube using Wire Coil

Convection heat transfer of air medium is more complex problem in any thermal product because of coefficient of air is less compare to other liquid. So we improve a heat transfer rate by air putting some turbulator with varying pitch and size and shape. So in many area of heat transfer like heat pipe, heat exchanger tube, etc. is more useable and valuable factor consider as an efficiency. So efficiency mainly depend upon a temperature difference of both end so we improve a rate of change of temperature in a tube. As a CFD post we solve a problem with various mass inlet at a same condition and gives a result in terms of Re, Nu, and Fr factor. The heat transfer rate through a circular tube is increased by varying various turbulators. The heat transfer performance and friction factor analysis is performed for a simple hollow circular pipe and circular of wire insert allows the higher heat transfer coefficient with relatively law flow resistance for the same pumping power for unique structure. The heat transfer analysis and friction factor of fluid flowing through a circular pipe at constant heat flux is studied using CFD. The study deals with effect on convective heat transfer rate by varying mass flow rate through different wire insert with various shape of wire. As a putting turbulator also increase power required to supply air so we find an optimum solution of it.
