Abstract: In the present experimental investigation, an experimental test is conducted on double pipe heat exchanger to establish the capability of Nano-fluids. cold side of a double pipe Heat exchanger antifreeze is mixed in water to enhance the Heat Transfer Coefficient. Experiments are conducted using distilled water on hot fluid side and Nano-fluids on cold side of the Heat Exchanger. Nano-fluids are prepared with TiO2 particles of 30 Nano meters size are dispersed in distilled water as per the standard procedures. The properties of these Nano-fluids are estimated using method of mixtures. Mass flow rate is measured using the collecting tank and stop clock. Friction factor is determined by the measured pressure drop across the test length of heat exchanger. The results are presented, enhancement of heat transfer is compared under the same set of operating conditions in tabular form of counter flow arrangement and heat transfer coefficient is compared in a counter flow arrangement with different methodologies. From the present experimental study it is concluded that by using Nano-fluids particles at 0.004% by volume Heat Transfer Coefficient increases from 15% to 45% when compared to pure Ethylene Glycol + Water in a double pipe heat exchanger in counter flow arrangement.
