Fractal analysis of Herschel-Bulkley fluid flow in a capillary
Meijuan Yun, Zheng Wei, Li Yun-Bao, Li Yu · Acta Physica Sinica · 2012
A fractal model for Herschel-Bulkley fluid in a capillary is proposed based on the fractal theory. The proposed model relates flow rate, velocity, starting pressure gradient and effective permeability to the rheological characteristics of fluid and the structural parameters of capillary, and all parameters in the proposed expressions have clear physical meanings. The analytical expressions reveal the physical principle for Herschel-Bulkley fluid flow in a capillary.
