Abstract:
The problem of setting artificial boundary conditions at outer
boundaries of a computational domain is considered. Discussed is
both the general problem of mathematical physics and the case of
external subsonic viscous gasflow. Nonreflecting boundary
conditions for the one-dimensional Euler equations are implemented
to numerical algorithms for modeling external flows, allowing for
nonlinearity, twodimensionality, and discretization effects.
Computations are performed of low Mach-number flows.
