Turbulent natural convection of a confined flow in a cubic enclosure: Effect of transient boundary conditions

Résumé

This paper presents the experimental study of a turbulent natural convection air flow occurring inside an enclosure with an inner block partially heated. Unsteady boundary conditions are applied on the heated face of the block. This allows to achieve boundary conditions and flow regimes that can be relevant for industrial unsteady heating or cooling purposes. The maximum Rayleigh number reached is equal to 1.98×10^9 which corresponds, for instance, to the flow regime encountered in the underhood of cars. For Rayleigh numbers from 0.25×10^9 to 1.98×10^9 , a dynamical analysis of the flow is conducted and similarity properties of the ascendant boundary layer are highlighted.
