Numerical study on thermo-hydraulic performance of cross flow tube bank with longitudinal fins

Research type: Masters thesis
Advisor: Prof. Ashwin S Dhoble
Colloborator: Dr. Chidanand Mangrulkar
Contributions

• Numerically investigated the variation of Nusselt number and friction factor for cross flow tube banks with and without rear side longitudinal taper fins at higher Reynolds Numbers.
• The effect of Reynolds number and geometric parameters of longitudinal taper fins, such as the length, base thickness and end thickness of fins on heat transfer and fluid flow characteristics of the cross flow tube bank in the staggered arrangement is investigated.
• Numerical simulations (conjugate heat transfer analysis with Reynolds-Averaged Navier-Stokes equations (RANS) turbulent models) were carried out using commercial CFD solver ANSYS Fluent.
