Abstract
Investigation of the dryout in upward water flow within the ranges of mass velocities 10-150 kg/m(2).s, pressures 0.1-1.6 MPa, and heat flux 50-420 kW/m(2) is reported. The distributions of wall temperature and wall temperature fluctuations on the length of the tube, the time var iations of flow temperature are obtained. The dependences of the bound ary vapor quality and the critical heat flux from mass velocity are di scovered. The mechanism of the heat transfer crisis at low mass veloci ties is also analyzed.
