Abstract On the basis of the data obtained in experiments onboard the Mirorbital complex (OC) in March and April 1999 with the ALICE-2 instrument, the influence of vibrations on heat propagation from a point-like source in the hexafluoride sulfur (SF6) under supercritical parameters is analyzed. The appearance of two different heat propagation regimes is found: along and across the direction of vibrations. Upon the occurrence of the second-type regime, the heating region first stretches in the direction perpendicular to the direction of vibrations and then propagates at a rate typical for the undisturbed case. The temperature relaxation process is analyzed, which takes place near the heater after its turn-off. The relaxation rate grows as the intensity of vibrations increases and the initial temperature tends to the critical one. The determining dimensionless parameters of the problem are suggested.
