Cfd and Thermal Analysis of Micro Fin Tubes to Optimize the Heat Transfer Rate Using Different Coolants

M. Jakarya, G. Srinivas


In this thesis, analytical investigations are performed to determine boiling characteristics in micro-fin tubes for different refrigerants R32, R404a, R410A and R600. The performance of the micro fin tubes is determined bychanging fin heights 5mm and 4mm.

3D models of the tubes are done in 3D modelling software Catia. CFD and Thermal analysis is performed on the tube to determine the heat transfer coefficients, pressure drop and heat transfer rates. Thermal analysis is performed for different materials Aluminium alloy, Copper alloy and Titanium alloy.

Analysis is done in Ansys 14.5.
