STUDY FOR 2 TYPES OF THERMOCONVECTIVE FLO WS ALONG A NONISOTHERMAL VERTICAL WALL IN A CAVITY

Study for two types of thermoconvective flows along a non-isothermal v ertical wall in a cavity, For the study of the natural convection alon g a non uniformly heated vertical wall in a cavity, we experimentally defined thermal curves. These curves were corrected by our semi-analyt ical corrective model. The two configurations, the first one instable, with a warm part lower to a cold part, and the other one, with warm a nd cold parts inverted are studied. We calculated convective flux dens ities and we showed a different comportment according to the configura tion. We proposed some values for the convective exchange coefficient in the case of regular profiles with no extreme. We recommended some c orrelations for the stable areas of the flow close to the active wall. (C) Elsevier, Paris.
