EXPERIMENTAL INVESTIGATION OF HEAT TRANSFER OF A LONGITUDINALLY STREAMLINED PLATE IN A LAMINAR BOUNDARY LAYER
Abstract
The present investigation was carried out on two identical circuits of a closed type. Water and air were circulated in one of them and transformer oil in the other. The diagram of the circuit is given. Two plates were investigated with dimensions of 10.25 x 40 x 0.65 and 50.25 x 40 x 0.65 mm, which were installed in the experimental section of the circuit in rectangular channel with dimensions of 200 x 100 mm. The side walls of the experimental section were made of organic glass which made it possible to see the flow process. Laminar flow of the plates was established during all experiments. Both plates were made of silico-nickel, 0.1 mm thick. The leading edges of the plates had the shape of a semicircle with a radius of about 0.33 mm. Copper thermocouples 0.15 mm in diameter were placed between the lower and upper walls of the plate. The thermocouple junctions were isolated from the plate surface by a thin layer of mica (0.03 mm) attached by BF-2 glue. (Author)
