Pressure-driven flow of a Herschel-Bulkley fluid with pressure-dependent rheological parameters
Panaseti, Pandelitsa; Damianou, Yiolanda; Georgiou, Georgios C.; Housiadas, Kostas D. (2018)The lubrication flow of a Herschel-Bulkley fluid in a symmetric long channel of varying width, 2h(x), is modeled extending the approach proposed by Fusi et al. [“Pressure-driven lubrication flow of a Bingham fluid in a ...

Viscoplastic Couette Flow in the Presence of Wall Slip with Non-Zero Slip Yield Stress
Damianou, Yiolanda; Panaseti, Pandelitsa; Georgiou, Georgios C. (2019)The steady-state Couette flow of a yield-stress material obeying the Bingham-plastic constitutive equation is analyzed assuming that slip occurs when the wall shear stress exceeds a threshold value, the slip (or sliding) ...
