Objectives Objectives of this assignment are: 1. Numerically simulate and analyse the heat transfer in a double pipe heat exchanger (Square Cross-section). 2. Numerically explore how this heat exchanger performance can be improved 3. Develop competency in using FLUENT with conjugate heat transfer 4. Develop analysis skills across analytical and numerical methods of assessing heat exchanger performance System to be modelled The hot working fluid passes through the inner pipe and cold fluid passes through the outer pipe. Note: Apart from double-pipe heat exchangers, you can use any other type of heat exchangers (Plate, PCB, etc). You can use any dimensions as well. The fluid flow properties for the hot and the cold fluid Hot fluid mass flow rate 0.5 kg/s Cold fluid mass flow rate 0.5 kg/s
