THERMOACOUSTIC PHENOMENA AT BOILING SUBCOOLED LIQUID IN CHANNELS

The problem of thermoacoustic phenomenon (ThAPh) of subcooled liquids boiling in channels is studied. The importance of the problem is well- known as high frequency pressure oscillations are responsible for dest roying and ruining not only tube sections, but apparatus and equipment units as a whole. The problem has not been explored well enough up un til now. The authors thoroughly explored previous investigations and c ontinued with detailed studying of the problem theoretically and exper imentally. As a result, they proposed an original theoretical model of the phenomenon which has been completely confirmed by the experiments . The results obtained by the authors can have very important practica l applications. (C) 1997 Elsevier Science Ltd.
