Description
Summary:This work deals with different models of a boundary layer of fluid flow used in numerical simulation in computational environment ANSYS. With the help of Computational Fluid Dynamics (CFD) was simulated the flow of the fluid and was monitoring the influence of the boundary layers on heat transfer and pressure drop. The basics of the boundary layer flow near a smooth wall, heat transfer and numerical simulation were described. Special attention was focused on possibilities of creation layers in computational grid. The analytical and numerical calculations of pressure losses and heat transfer coefficient were performed on straight circular pipeline with different types of boundary layers. The results were compared with each other, then between two different types of used grid, and evaluated, where the analytical results were set as referential values.
