Turbulence modeling is the construction and use of a mathematical model to predict the effects of turbulence. Turbulent flows are commonplace in most real life scenarios, including the flow of blood through the cardiovascular system, the airflow over an aircraft wing, the re-entry of space vehicles, besides others. In spite of decades of research, there is no analytical theory to predict the evolution of these turbulent flows. The equations governing turbulent flows can only be solv… WebMODELING OF NON-STRATIFIED MIXTURE FLOWS (Pseudo-homogeneous flows) Uniform (or almost uniform) distribution of transported solids across a pipeline cross …
