Abstract :

Heat Transfer Enhancement or intensification is one of the most important technical challenges faced by numerous industries like manufacturing, automobiles, etc. It is one of the key factors in heat exchangers design while working to design compact devices. The requirement of compact heat exchangers like shell and tube heat exchanger is very concern where the heat transfer area is low. The conventional methods of cooling like fins and microchannels have already extended to their limits. As the traditional fluids of heat transfer such as water, oil, and ethylene glycol are innately poor heat transfer fluids, the new technique of dispersing the nanoparticles in the base fluid called nanofluids has emerged in enhancing the heat transfer rate. This research work presents the analytical investigations are carried on the heat exchanger using forced convective heat transfer. Two different types of nanoparticles TiC and MgO individually at different volume concentrations of 0.1%, 0.3%, 0.5% using water as base fluid is used. The fluid flow is considered to be turbulent. Experimental results and CFD analysis are performed on the shell and tube heat exchanger by applying the properties of the above nanofluid concentrations to obtain the heat transfer coefficient and heat transfer rate. For this, a 3D model of the heat exchanger is done in CREO 3.0 and imported to the ANSYS(FLUENT). Theoretical calculations were carried to obtain the properties for nanofluids which are used as inputs for analysis.
