Abstract

Nanofluids are colloidal mixtures of base fluids such as oil, ethylene glycol, water, or a combination of these base fluids and metal, metal oxide, or ceramic nanoparticles. The concept of Nano coolants is used in jacketed vessel to increase the thermal conductivity of water. The Nano sized powder will then be distributed into a fluid with the aid of strong magnetic force agitation, ultrasonic agitation, etc. Due to the high surface area and surface activity nanoparticles has the tendency to aggregate. Lower concentration of nanocoolant will increase the heat transfer rate without increase in the pumping power and pressure drop. The Concentrations of nanofluid prepared are 0.001%. Cupric oxide Nanoparticle mixture was prepared by blending the respective nanoparticles in water using a bath-type sonicator. The heat transfer rate of cupric oxide nanofluids in a jacketed vessel was calculated and compared with base fluid. The increase of heat transfer coefficient using 0.001% Cupric oxide Nanoparticle was found to be 160.56 % when compared with basefluid.
