Vortex intensification in convective cells

Autor: M. E. Povarnitsyn, M. F. Ivanov

Publikováno v: Fluid Dynamics. 39:729-734

The intensification of single vortices in convective flows swirled by the Coriolis force is studied numerically. The initial disturbances, specified against the background of a steady cell, are coaxial with the cell flow and have various swirl direct

A wide-range model for simulation of aluminum plasma produced by femtosecond laser pulses

Autor: M E Povarnitsyn, N E Andreev

Publikováno v: Journal of Physics: Conference Series. 774:012105

We use a wide-range model of thermodynamic, transport and optical properties for simulation of laser-induced dynamics of aluminum plasma. The model describes the laser energy absorption, electron thermal conductivity and two-temperature effects of el
