CFD ANALYSIS OF SHELL AND TUBE HEAT EXCHANGER WITH AND WITHOUT BAFFLES BY USING NANO FLUIDS

Heat exchanger is a device used to transfer heat between one or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. In this work, different NANO fluids mixed with base fluid water are analysed for their performance in the shell and tube heat exchanger without baffle and with baffle(900,300 and helical type baffle). The NANO fluids are Aluminium Oxide and Titanium carbide for two volume fractions 0.4, 0.5. Theoretical calculations are done determine the properties for NANO fluids and those properties are used as inputs for analysis. 3D model of the shell and elliptical tube heat exchanger is modelling in CREO parametric software. CFD analysis is done by ANSYS software
