Research output: Contribution to journalArticlepeer-review


Thermal homogenization is significantly accelerated near the critical point because of the so-called piston effect. In essence, the piston effect is a thermomechanical effect. We study the momentum and energy transport in supercritical CO2 by numerically solving the governing hydrodynamic equations. The results show explicitly the thermoacoustic nature of the process, which patently deviates from what the classical Fourier conduction model predicts.
