What is Mixed Convection from Two Horizontally Aligned Hot and Cold Circular Cylinders in a Vented Square Enclosure about?

The mixed convection heat transfer from two horizontally aligned cylinders with one hot and one cold cylinder inside a vented square enclosure with openings on the upper and lower surfaces has been numerically investigated. The simulated behaviour of heat and flow fields has acquired the solutions using the Navier-Stokes equation and energy equation for steady, laminar and incompressible flow properties. Considering a diverse range of opening sizes O = 0.125–1, spacing sizes S = 0.3–0.45, Richardson number Ri = 0.1–10 and Reynolds number Re = 50–400 were covered with fixed Prandtl number Pr = 0.72. Velocity contours and isotherms with the average and local Nusselt numbers (Nu) have been displayed with various parameters. The method of solution uses the finite volume method (FVM). Pressure–velocity coupling and the SIMPLE method were used to solve the momentum and energy equation via the CFD software ANSYS/ FLUENT 2021 R1. The numerical solution shows the linear relationship between increasing the average Nu value with increasing Ri, Re and opening sizes O of the vents. Moreover, the increasing of spacing size to S = 0.375 positively enhances the value of average Nu around the hot c
