Modeling of convective flows in CFD-packages

The results of numerical studies of the formation of convective flows in a cylindrical fluid layer with localized heating in the central part are demonstrated. For the numerical solution of the problem we used finite element software suite ANSYS. Calculations were carried out in two different software packages: CFX and FLUENT. Integral characteristics of convection flow are presented. A comparison of solutions obtained by different solvers, with the experimental data is shown.
