T1 Development of an Improved Mode of Heat Transfer of a Hydrocarbon Heat Carrier under a Supercritical Pressure in an External Acoustic Field of a Standing Wave Formed by Thermoacoustic Self-Oscillations of Pressure JF Heat Transfer Research JO HTR YR 2006 FD 2006-04-25 VO 37 IS 3 SP 199 OP 210 AB The data on experimental investigation and calculation of the local coefficient of heat transfer of toluene, which, in the case of mixed convection and at a supercritical pressure, flows in small-diameter vertical tubes (d = 3−4 mm) at a constant heat flux on the wall (a descending flow) are presented. Experiments were carried out in the field of convective heat transfer accompanied by generation of high-frequency pressure oscillations of a heat carrier. It has been established that high-frequency pressure oscillations represent standing pressure waves. It is shown that the distribution of the wall temperature and of the heat-transfer coefficient over the tube length depends on the local distribution of pressure in a standing wave. The boundary of the beginning of thermoacoustic oscillations has been found. PB Begell House LK https://www.dl.begellhouse.com/journals/46784ef93dddff27,0c96fb77540f3569,31ab5791680d0237.html
