Steady non-Newtonian flow past a circular cylinder: a numerical study. (English) Zbl 1065.76013
From the summary: Using a stream function/vorticity formulation, steady incompressible flows of non-Newtonian fluids past a circular cylinder are investigated for power law indices \(n\) between 0.2 and 1.4, blockage ratios of 0.037, 0.082 and 0.164, and the Reynolds numbers Re of 1, 20 and 40. The governing equations are solved by a second-order accurate finite difference method to determine the drag coefficient, wake length, separation angle and flow patterns, and to investigate their dependence on power law index, blockage ratio and Reynolds number.
