Abstract
In this paper, the heat transfer coefficient and pressure drop on the shell side of a shell and tube heat exchanger have been experimentally obtained for two different fluids that is for water and copper oxide nano fluid. Also experimental data has been compared with theoretical data available. Water is our hot fluid, copper oxide mixed with water –which is our nano fluid is treated as cold water .Flow rate of hot water is maintained between 15-18 lpm. The volume fraction of copper oxide nano fluid is varied from 10-30%.Experimenatal results such as shell and tube heat exchanger effectiveness, overall heat transfer coefficients are calculated.
Keywords: Shell and tube heat exchanger, heat exchanger design, sedimentation process, nano fluids, overall heat transfer coefficient, effectiveness, pressure drop
