HEAT TRANSFER IN SUPERCRITICAL FLUIDS: THE CASE OF HIGH-POWER HEAT RELEASE

Краткое описание
Non-stationary heat transfer in supercritical fluids over short periods of time and at small spatial scales has been studied experimentally. The aim of this study was to clarify the characteristic features of the heat conduction mechanism under significant heat loads. For this purpose, the controlled pulse heating of a fast-response wire probe method was used. The characteristic heating time was a few milliseconds, and the heat flux density through the probe surface was increased up to 20 MW/m2. For all substances studied, the threshold decrease in the heat transfer intensity was revealed in the course of crossing the vicinity of the critical temperature along the isobar. This effect was more pronounced when the pressure value (p) was closer to the critical pressure (pc). The effect was observed over a wide range of reduced pressures up to p/pc = 3. The final solution to the problem of reconciling our result with peaks in the thermophysical properties, which are known from stationary experiments in the near-critical region, has not been found thus far.
