During the tests of the first jet plane in Paris, December 1936, the Romanian engineer Henry Coanda was the first to observe this phenomenon, occurring when the flames of the engine passed through a flap. The logo of the Olympiad illustrates the Coanda flow of a fluid.
The second pyrometer, of identical function f, is aimed at that part of the wall, whose temperature, Ow , equals the average temperature of all the walls. The signal of this second pyrometer is : S2 = Ew .f (6w) (11 .15) Correcting both signals in the function of charge emissivity,[r]
Heat exchangers are a device that exchange the heat between two fluids of different temperatures that are separated by a solid wall. The temperature gradient, or the differences in temperature facilitate this transfer of heat. Transfer of heat happens by three principle means: radiation, conduction[r]
