Turbulent Natural Convection in an Enclosure at Varying Rayleigh Number
Keywords:
Buoyancy, Natural Convection, Reynolds Stresses, Turbulent heat flux, Turbulence Modeling.Abstract
Most fluids used in technical applications are of low viscosity; hence, fluid flows encountered in engineering applications are mostly turbulent. Parameters that influence the distribution of the flow field of turbulent flow regimes thus significantly affect the performance of many thermal systems. In this study, we analyze the distribution of the flow field of a Boussinesq buoyancy-driven turbulent airflow for
