B. Kirubadurai, K. Ramesh

Abstract :

Heat transfer fluid have inherently low thermal conductivity that greatly limits the heat exchanger efficiency. Many research activities are carried out to the thermal transport properties of the fluid by adding more thermally conductive solid into liquid. Liquid dispersions of Nano particle, which has been termed “Nano fluid”, exhibit substantially higher thermal conduct ivies than those of corresponding base fluid.in this work new Nano fluid system has been developed by using silicon nitride Nano particle to synthesize Nano fluid in a shell and tube heat exchanger. The thermal transport properties of Nano fluid, including thermal conductivity, viscosity, heat capacity and heat transfer coefficient in convective environment are characterized and modelled. Since heat capacity of heat transfer fluid is one of the major thermal transport properties, it is described with help of the Einstein-Bachelor model. The result shows that Nano fluid possess improved thermal transport properties and it has been experientially proved that Nano fluids have the potential to use as next generation advanced heat transfer fluid.
