Numerical Simulation Of Turbulent Natural Convection And Heat Transfer In A Rectangular Enclosure Using The 𝒌 − 𝝎 Model

ABSTRACT Turbulent flow is a type of fluid flow in which the fluid undergoes irregular fluctuations. The velocity of the fluid at a point is continuously undergoing changes in both magnitude and direction. Turbulent natural convection has been studied both numerically and theoretically. It plays an important role in the field of heat transfer and buildings environment. A numerical study was performed on a rectangular enclosure with varying Rayleigh numbers to determine velocity, temperature distributions and turbulent intensities of a two dimensional buoyancy driven turbulent flow. The vertic…
