Numerical study of heat transfer characteristics on tandem cylinders, inline and staggered tube banks in cross-flow of air

摘要

Numerical analysis of the heat transfer on tandem cylinders, inline and staggered geometries in cross flow of air are investigated for different geometry and flow conditions. finite element method is sued to solve Navier-Stokes and energy equations. Local variations are presented for tandem cylinders geometry with L/ D=1.13, 2,3,6 and Reynolds number is fixed as 400. Three isothermal cylinders for Staggered geometry, four isothermal cylinders for inline geometry were placed in a Wide channel and S_r x S_1 was fixed as 2x2 and Reynolds number was varied as the Value of 80, 120, 200.
