Quasi-gasdynamic algorithm in the polar coordinate system and a numerical simulation of instabilities in accretion disk flow
Abstract:
Quasi gas-dynamic equations in the polar coordinate system together with the finite-volume numerical scheme are constructed. Obtained algorithm is used for the numerical simulation of the large-scale instability development in the gas dynamic accretion disk around a
gravity center.
