... and theoretical investigation of highly subcooled ethanol in an annular flow-passage duct under the conditions of pulsed heat generation in the wall cooled by liquid flow are presented. The formation of a vapor film on the heater wall and long-lasting pressure oscillations of high amplitude in the duct (the self-oscillatory regime) have been observed in experiments. A mathematical model of the ethanol boiling up has been developed to take into account the evaporation of the overheated liquid near the ...

In experiments with the vertical channel, pulsations of a vapor film on a heater wall, accompanied by pressure oscillations with growing amplitude (the self-oscillatory mode), were observed. The mathematical model, which describes the non stationary process of boiling of ethanol in the channel, is presented. Model takes into account pulsations of a vapor ...
