Some Mechanisms of Vortex Formation in the Flow Around Bodies Moving in the Atmosphere

摘要

We present the generalized differential equations of aerogasdynamics for FV full-scale motion and the vector equation for vortex motion. We substantiated the relation that evaluates the vortex force work. We carried out also the numeric calculations taking into account the influence of additional stress tau [1], and showed that there exists the dissipation vortex function both for the non-viscous and the viscous medium models. It makes it possible to vary entropy not only at the transition through shock waves but also in the entire perturbed flow field. We substantiate the necessity for taking into account medium compressibility.
