Abstract

The basic methods of constructing a hexagonal mesh in Cartesian coordinates for a three-dimensional cylindrical region are considered. Several variants of grids, describing the inner region of the vortex tube, are presented. Advantages and disadvantages of presented meshes are discussed. The gas dynamics in a vortex tube is described by the mathematical model, which consists of Navier-Stokes equations for compressible viscous fluid, and the perfect gas law. The solution is done with the usage of the PIMPLE algirithm in OpenFOAM. The simulation results on different grids, including the result with the inversion of the temperature field, and their discussion are presented.
