Аннотация:The purpose of the present numerical simulation is to analyze density fragmentation process in small molecular clouds shocked by a shock wave of supernova blast
remnants. We consider dynamical formation of MC structures associated with KelvinHelmholtz and Richtmayer-Meshkov instabilities taking place in a zone of the cloud and
interstellar medium interaction. Form driving effects for one and two cloud systems are
studied. The MC gas flow evolution is derived by solving the time dependent equations of
mass, momentum, and energy conservation. High resolution numerical grids (more than
two billion nodes) were used in parallel calculations on multiprocessor hybrid computers.
The first of modelling task was a single cloud SW/MC interaction. In the second case
two initially spatially perceptible clouds with pre-established gravitational fields interact
with the post-shock medium. The peculiarities of cloud-clump-shell fragmentation and
formation of generated structures are discussed.
