Abstract: The results of numerical simulation of interstellar gas clouds, performed in the framework of quasi-gasdynamic (QGD) algorithm for the first time, are presented. The decay of a Taylor–Green vortex and the quasi-stationary flow with initial condition in the form of a random solenoidal velocity field with energy source are considered. The typical parameters of the interstellar gas clouds, in which stars can be formed, were used. The results obtained shows the capabilities of the QGD algorithm for the simulation of sparse large-scale turbulent clouds, which include the supersonic zone of the flow.
Keywords: quasi-gas dynamic (QGD) system, turbulent flows, interstellar gas.
