Краткое описание

Many turbulent flow processes of engineering importance exhibit highly complex interacting phenomena, such as mixing, heat and mass transfer, chemical reaction, etc. hi curved ducts of relevance in heat exchangers, cooling passages of gas turbines and automobile engines, turbulent flow and heat transfer give rise to the existence of so-called "camel back" shapes in the streamwise mean velocity and temperature distribution of the curvature, hi swirled combustion flows, turbulent flow and mixing are dominated by an extremely 3-D complex behavior of great interest for many combustion engines purposes. Both cases are complex configurations and challenging for turbulence models, hi this paper the ability of advanced explicit algebraic formulation to capture such flow and mixing properties using economical costs required for engineering design purposes is successfully demonstrated.
