Study on the Drag Reducing Channel Fluids by Experiments and DNS Using Giesekus Model

Study on the Drag Reducing Channel Fluids by Experiments and DNS Using Giesekus Model

Both experimental and numerical studies are simultaneously performed for fully developed water and surfactant solution channel flow. The comparison aims at the surfactant solution flow in experiment with mass concentration of 25 ppm at Re = 1000 and Giesekus model with Weissenberg numbers of 10 and...
