Abstract

In the present work the analysis of three different copper tubes (smooth tube, two corrugated tubes with corrugated ratio (z/d=1 and 0.5)) in a shell and tube heat exchanger done by ANSYS FLUINT14.0. This work deals with theoretical investigation was to evaluate the benefit of changing the shape of inner tube in the heat exchanger and the improving the heat transfer using water as the working fluid in the first case, then using a Nano fluids as a heat transfer working fluid. The conditions used in the simulation are in the two case the hot side flow rate range from (1 to 5 LPM) with three different temperature (40, 50 and 60°C). The cold side flow rate range (3 to 7LPM) for water and (3.2 to 7.2LPM) for nano fluid because of the change in density by added nanoparticles and at 25°C for the two cases. The simulation show results of enhancement in heat transfer rate ranging from (58.24% to 59.55%) at a temperature of 40°C, (55.62% to 58.09%) at a temperature of 50°C and (54.44% to 59.17%) at a temperature of 60°C, for both corrugated tubes with respect to smooth tube by used water as cooling fluid. By using Nano- fluid the enhancement in heat transfer are (60.14% to 61.44%) at a temperature of 40°C, (58.36% to 62.01%) at a temperature of 50°C and (56.46% to 63.15%) at a temperature of 60°C, for both corrugated tubes with respect to smooth tube.
