THE PARTICLE IMAGE VELOCIMETRY TECHNIQUE WAS EMPLOYED TO MEASURE VELOCITY FIELDS AT THE ENTRANCE REGION OF A ONE-SIDED HEATED VERTICAL CHANNEL IN NATURAL CONVECTION. THE EXPERIMENTS WERE AIMED AT REVEALING THE EXTENT OF THE REGION OF INFLUENCE OF THE CHANNEL ON THE ENTRANCE FLOW FIELD, AND TO PROVIDE INFORMATION ON THE SHAPE OF THE VELOCITY PROFILE AT THE CHANNEL ENTRANCE PLANE. THREE OPERATING CONDITIONS OF THE CHANNEL WERE INVESTIGATED CORRESPONDING TO THREE VALUES OF THE CHANNEL RAYLEIGH NUMBER. THE RESULTS OBTAINED REVEALED THAT THE INFLUENCE OF THE CHANNEL DOES NOT EXTEND TO A LARGE REGION AT THE ENTRANCE OF THE CHANNEL. THE VELOCITY PROFILE AT THE ENTRANCE WAS SHOWN TO HAVE A SIGNIFICANT HORIZONTAL COMPONENT. |
