Bingham plastic model equation
WebApr 10, 2024 · using modified Blasius equation for estimating friction factor and using hydraulic diameter definition. Total average absolute percentage errors between 3 - 5% have been obtained. KEYWORDS... In materials science, a Bingham plastic is a viscoplastic material that behaves as a rigid body at low stresses but flows as a viscous fluid at high stress. It is named after Eugene C. Bingham who proposed its mathematical form. It is used as a common mathematical model of mud flow in drilling engineering, and in the handling of slurries. A common example is toothpaste, which will no…
