摘要：

Some problems of supercritical fluid dynamics and heat transfer under various gravity conditions are solved experimentally and numerically. Ground-based experiments coupling with numerical simulations are performed to investigate dynamic and thermal effects in supercritical fluid subjected to heat supply. Numerical simulations of the piston effect and thermal gravity-driven convection in the fluids with variable physical properties are carried out. The effect of variability of properties caused by density and temperature inhomogeneities on the rate of the piston effect and convective patterns is discussed.
