| description | The rapid development of high power electronic, energy systems has led us to the fact that the performance of these systems is limited by their cooling capacity. Spray cooling is one of the most effective methods for cooling heated surfaces. The efficiency of heat transfer from the heated surface depends on many of the integral parameters of the flows (flow rates of liquid, gas, their thermophysical properties, surface properties), and on the size and distribution of droplets formed in the nozzle, their density and velocity, the properties of the surface and material of heated objects, and the temperature value. In this work, the efficiency of heat transfer from a heated copper surface by a rarefied gas-spray flow created by two similar types of nozzles in the mode of a small amount of liquid supplied is experimentally studied. |
