The Interaction of a Liquid Nitrogen Jet with a Surface in Boiling
要約
The work presents the results of experimental investigation of heat transfer in interaction of a liquid nitrogen jet 3 mm and 4 mm in diameter (the jet velocity is from 1.5 m/sec to 16.5 m/sec, the angle of flow impingement is 90°C) with a preliminarily heated (up to 450 K) copper and steel surface. The temperature of the liquid in the experiment was maintained equal to 77.4 K at atmospheric pressure. The results of visual observations showed that a jet before its incidence on a surface is continuous and the region of the interaction of the jet with a surface is stable and forms a spot of contact of diameter from one to five diameters of the jet.
