Abstract: In a conventional plate heat exchanger, increase in heat transfer area directly affects the size of heat exchanger by making it bulky. To overcome this limitation and to test the capability of compact heat exchanger namely corrugated plate heat exchanger, there is a need to increase the heat transfer coefficient of the base fluid. Preferably, addition of Nano particles along with the provision of corrugations on the plates will lead to an increase in effectiveness of the heat exchanger. This study is carried to enhance heat transfer of water by addition of Nano fluids and test the test rig for parallel flow arrangement and counter flow arrangement for different mass flow rates of hot fluid. design of heat exchanger is done based on sizing, that is determination of heat transfer parameters, number of thermal plates required and physical dimensions. It is observed that there is a slight drop in effectiveness with increase in heat capacity ratio. For water as a working fluid the value of effectiveness varies from 0.66 to 0.80 while that of for Nano fluids the value of effectiveness varies from 0.70 to 0.82.
