Abstract
The spatiotemporal density and temperature variations induced by heating the walls of a closed domain filled with supercritical fluid are studied experimentally and numerically. The experimental results were obtained from the specially designed laboratory experiment carried out with the use of the Alice-1 instrument. The numerical results were obtained by the direct solving of the complete Navier-Stokes equations supplemented by the van der Waals or perfect gas equations of state. The numerical instrument proposed is shown to be capable to adequately describe the time dependences of density and temperature fields on short-term (
