Experimental Study for Data Validation Regarding the Flow Movement in Natural Convection in an Asymmetrical Heated Vertical Channel

Abstract:

The present paper presents an experimental study, regarding the dynamics of movement in natural convection in an asymmetrically heated vertical channel. The channel was immersed in a tank filled with water at a temperature of 15 °C. The study focuses on one hand, on the radiated heat output from the heating plate, and on the other hand, on the thermo-physical boundary conditions from the inlet and the outlet of the channel. These aspects give great problems in natural convection if limited to a single channel as a field of study. The experimental study was conducted to validate numerical results, in similar conditions. The size variation of the recirculating zone, temperature and speed in the channel were analyzed through the PIV method (Particle Image Velocymetry) using the equipment provided by Dantec Dynamics and the analysis program "Dynamic Studio".
