A constitutive equation （named as FX equation） was developed and applied to a cylindrical pipe flow of a shear-thickening fluid. A blunt velocity profile and its volume flow rate were calculated. The flow was non-viscous （potential） in the central part of the pipe （i.e. the central core or the central plug-flow）, and became more and more viscous towards the wall of the pipe after a specific radial distance, which was determined by a critical shear rate of γF （named as Fung＇s shear rate）. Furthermore, combining the FX equation with the original Casson＇s equation, the author obtained a modified Casson＇s equation by introducing γF.展开更多
