Abstract

This paper deals with the flow of bitumen binder in a cylindrical tube described by the Hershel-Bulkley fluid. The dependence is suggested for the fluid flow rate and the pressure drop. Dependences are also determined for the radial velocity distribution and effective viscosity. It is found that at a low pressure drop, the non-Newtonian properties of the medium lead to a significant hydraulic resistance due to the internal structure. With an increase in the pressure drop, the hydraulic resistance of the flow decreases.
