Abstract

cooling is indispensable for maintaining the desired performance and reliability of a wide variety of products, such as computers, car engines and high powered laser. With the increase of heat loads and heat uses caused by more power and smaller sizes for these products, cooling is one of the top technical challenges faced by the industries like microelectronics, transportation, manufacturing, metrology and defense. However, with continued miniaturization, increasing heat dissipation and inherently low thermal conductivity is a primary limitation in developing energy coefficient heat transfer fluids that are required for ultrahigh performance cooling in new generations of products. Therefore, the cooling issue will intensify in many industries from electronics and photonics to transportation, energy supply, defense and medical. Development of the nano materials technology has made it possible to structure a new type of heat transfer fluids formed by suspending nano particles (diameter less than 100nm) in conventional base fluids like water and ethylene glycol. The nano particles suspended in a base liquid are in random motion under the inuence of several acting forces, which is a random function of time, and reacts the atomic structure of the medium. The exact role of this stochastic motion of nano fluid and energy transport inside the nanofluid is not well understood. Due to rapid fluid mixing reacts strengthens the energy transport inside the nanofluid by modifying the temperature proles. Experimental data indicates that particle size, volume fraction and properties of the nano particles inuence the heat transfer characteristics of nano fluid. Now, according to thermodynamics, the coefficiency of surface condenser is based on mass ow rate of cooling water. To reduce the mass flow rate of cooling water in surface condenser, some of the nano fluid are insert with them and measure various parameters like inlet & outlet temperature, mass flow rate etc. After that, by com-paring the costs of normal sea water and sea water with mixed nanofluid, a particular mass flow rate will be decided and from that volume concentration. From this mass flow rate and volume concentration of nano fluid, the optimization of condenser cost is down.
