Summary:Title screen
The article presents the results of studies of the characteristic features of heat transfer by rapeseed oil/water emulsions that accompany powerful heat release on their surface. Two methods have been employed to provide short-term penetration into the region of superheated states of the dispersed phase (water) preceding an explosive boiling-up of the emulsion: the pulse heating of a wire probe and the heating of a droplet in a gas flow. The experiments have been performed in wide ranges of variables, including the probe/gas temperature (350–950 K), the heating rate (102; 105–106 K/s), the water content (0–10 wt%), and the pressure in probe experiments (from 0.1 MPa to 5p/pc), where pc is the critical liquid–vapor pressure of the substance. Based on the primary data of the pulse experiment, the heat transfer coefficient as a function of time, KT(t), has been determined, depending on the water content and the reduced pressure p/pc, as well as an approximation for the critical parameters (pc, Tc) of rapeseed oil. The fundamental effect of explosive boiling-up on the change in the coefficient KT(t) has been revealed. The results contribute to the development of fuel technologies based on micro-explosive fragmentation of composite liquids and to verification of the choice of coolant for micro-devices, the action of which is accompanied by powerful heat generation
