The Effect of Inlet Subcooling on Two-Phase Flow Dynamic Instabilities In-Tube Boiling Systems,cs are determined by a numerical solution of the governing equations as derived from the Drift-Flux model. The transient characteristics of the two-phase flow are obtained for various parameters and the results are presented in tabular form. The numerical solutions are determined using an explicit f

Heat Transfer in a Liquid Nitrogen at High Centrifugal Acceleration Fields,s, such studies were carried out using ordinary (non-cryogenic) liquids (freon, ethanol, water, etc.). The study of heat transfer in cryogenic liquids within the fields high intense mass forces was stimulated by development of cryogenic electric machine industry. The main attention was paid to heat

Recent Advances in Cryobiology Using Calorimetry,r centuries[9]. Hypothermic conditions are encountered either naturally as a part of the ambient climate or artificially in conjunction with cryosurgical or cryopreservation procedures. In both cases the basic physico-chemical phenomena which govern the reaction of the living systems are complex and
