Study of heat flux in Heat Exchangers by using ZnO Nano fluid

Heat transfer in anticipation of the heat transfer between two objects because of the temperature difference arises deals.Nano fluids are a class of heat transfer fluids which are created by dispersing solid nanoparticles in traditional heat transfer fluids. This work describe an empirical design and a numerical method to illustrate the forced convective heat transfer using traditional fluid and Zinc Oxide/Water Nano fluid in double-pipe heat exchanger utilizing commerciallyavailable equipment. The test results are shown that the heat transfer rate and heat transfer coefficients of the Nano fluid is higher than thatof the base liquid (i.e., water). Increasing in the overall heat transfer coefficient is more forcible at high cold flow rate for a given hot fluidflow rate. The heat transfer rate and heat transfer coefficients, finally increase with increase in mass flow rates of hot and cold streams.
