Turbulent gas flows in channels of different cross-sectional shapes with mass flow

The issues of mathematical modeling of turbulent flows in channels with blowing of different cross-sectional shapes are considered. As a result of a series of computational experiments using the OpenFoam tools, the influence of the channel shape on the realized features of flows is investigated. A mathematical model of conjugate heat transfer for the channels under consideration is proposed. Comparison of the results of numerical simulation with the known experimental data has shown the correctness of the proposed models, schemes and algorithms. The topological features of the structure of viscous compressible heat-conducting gas flow in the channels with mass flow of complex shapes have been studied, including the features of the velocity profiles formed in the outlet sections of the channels, the results of calculating the coefficient of non-uniformity of velocity have been described.
