Explicit equations for laminar flow of Bingham plastic fluids

WebFeb 11, 2024 · The Bingham Plastic model also has two empirical constants. Here, we've written those constants as S y and R C, representing the yield stress and coefficient of rigidity for the fluid. The fluid yield stress can also be written as τ y, τ B, or τ 0. Similarly, the fluid coefficient of rigidity may be written as µ ∞ or η B. WebDec 1, 1999 · A friction factor equation for yield fluids (yield-pseudoplastic, yield-dilatant, Bingham) was derived from flow equation under turbulent pipe flow conditions. The rheological characteristics of the yield fluid were described by Herschel and Bulkley model. WebIf we look at a graph of its shear rate (how fast the fluid is moving) vs shear stress (resistance to flow), a Bingham Plastic fluid follows a linear trend (y = 0.0197x + 52.68). cite a web image
