Abstract

Modeling of the vortex tube for several variants of the size and shape of inlets of the swirl is carried out. A mathematical model of the process is written. Computational modeling was based on the LES method using the PIMPLE algorithm in the OpenFOAM computational package. Considerable attention was paid to using uniform orthogonalized meshes, while the shape and size of the swirl of the swirl was determined by the feature of the mesh constructed. It is shown that, under certain initial conditions, the effect of thermal stratification can be inversed for some forms of the swirler.
