Supercritical Heat Transfer, the piston effect

I'll insert the figure later.

Figure 3. Thermalisation in microgravity of a supercritical fluid (SF 6 ) after a heat pulse. T1, T2 and T3 are measuring thermistors. The thermalisation by the piston effect is fast and complete, whereas the peak temperature due to heat conduction is reached much later. (Courtesy of D. Beysens, CEA, Saclay, France)
