WebOct 1, 1996 · Abstract. The present work attempts to characterize the flow of shear-thinning power-law fluids past a flat plate as the angle of attack is varied. The effects of Reynolds number, shear-thinning characteristics and angles of attack on drag and lift of the flat plate were investigated, both experimentally and numerically. WebThere are, of course, non-Newtonian fluids where the viscosity changes with the application of shear force. These are classified as follows: Pseudoplastic - decrease in viscosity. Thixotropic - time dependent decrease in viscosity. Dilatant - increase in viscosity. Rheopectic - time dependent increase in viscosity.
