Helium flow in a confined region caused by heating under zero gravity: approaches based on molecular kinetics and mechanics of continuous media

Helium flow in an enclosure caused by sudden heating of the enclosure walls is considered. Boltzmann’s equation and complete time-dependent Navier–Stokes equations with appropriate boundary conditions are integrated numerically. It is shown that the results of calculations obtained by using these me...

Description
Summary:Helium flow in an enclosure caused by sudden heating of the enclosure walls is considered. Boltzmann’s equation and complete time-dependent Navier–Stokes equations with appropriate boundary conditions are integrated numerically. It is shown that the results of calculations obtained by using these methods for a steady-state flow are close.
