Based on the system of two-dimensional axisymmetrical 
continuity equations, Navier-Stokes and energy equations, and 
the equations of selective heat radiation transfer, a computational 
model is constructed and conditions of unsteady subsonic flows in 
a cylindrical channel of a power unit of the laser-plasma accelerator 
type are investigated. The governing parameters of the model are calculated, 
at which numerical solutions can be obtained to describe steady laminar 
gas flow in the neighborhood of the region of heat release, nonstationary 
oscillatory motions, and nonstationary vortex motion.
