Abstract
Flow and heat transfer in a flat confuser is numerically modeled using a three-parameter differential RANS turbulence model supplemented with a transport equation for turbulent heat flow. The influence of the angle of inclination of the confuser wall and the Reynolds number on the characteristics of flow and heat transfer in the boundary layer is considered. The calculation results are compared with the experimental data.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
