الملخص EN
The effect of radiation on laminar and turbulent mixed convection heat transfer of a semitransparent medium in a square enclosure was studied numerically using the Finite Volume Method.
A structured mesh and the SIMPLE algorithm were utilized to model the governing equations.
Turbulence and radiation were modeled with the RNG k - ε model and Discrete Ordinates (DO) model, respectively.
For Richardson numbers ranging from 0.1 to 10, simulations were performed for Rayleigh numbers in laminar flow (104) and turbulent flow (108).
The model predictions were validated against previous numerical studies and good agreement was observed.
The simulated results indicate that for laminar and turbulent motion states, computing the radiation heat transfer significantly enhanced the Nusselt number (Nu) as well as the heat transfer coefficient.
Higher Richardson numbers did not noticeably affect the average Nusselt number and corresponding heat transfer rate.
Besides, as expected, the heat transfer rate for the turbulent flow regime surpassed that in the laminar regime.
The simulations additionally demonstrated that for a constant Richardson number, computing the radiation heat transfer majorly affected the heat transfer structure in the enclosure; however, its impact on the fluid flow structure was negligible.
