| Description |
The mixed convection heat transfer around five in-line isothermal square cylinders periodically arranged within a vertical duct is numerically investigated in this paper. Spacing between two cylinders is fixed at one width of the cylinder dimension and the flow confinement of various degrees are studied for the blockage ratios of 0%, 10%, 25%, and 50%. The buoyancy aided/opposed convection is examined for the Richardson number ranges from –1 to +1 with a fixed Prandtl number 0.7 and Reynolds number 100. The transient numerical simulation for this 2-D, incompressible, laminar flow, and heat transfer problem is carried out by a finite volume based commercial computational fluid dynamics package FLUENTTM. The representative streamlines and isotherm patterns are presented to interpret the flow and thermal transport visualization. Additionally, the time and surface average skin friction coefficient, drag, and lift coefficients as well as the time and surface average Nusselt number for representative cylinders are determined to elucidate the effects of Reynolds number and Richardson number on the flow and heat transfer phenomena.
