Abstract The flow of a non-Newtonian, power-law fluid, directed normally to long, two-dimensional horizontal bodies, is considered in the present note. It is found that for low Reynolds numbers Re ≤ 0.1 and a low power-law index shear-thinning fluids the drag coefficient always obeys the relationship c D = A - Re , whereas at a high power-law index shear-thickening fluids the drag coefficient tends to become identical for all bodies irrespective of their cross-section form.
