Bingham plastic velocity profile
WebAug 13, 2024 · The velocity profiles calculated from equation (3.7a) are shown in Figure 3.3, for various values of n. Compared with the parabolic distribution for a Newtonian fluid (n = 1), the profile is flatter for a shear-thinning fluid and sharper for a shear-thickening fluid. The velocity is seen to be a maximum when r = 0, i.e. at the pipe axis. WebThe velocity profile for a Bingham plastic fluid flowing (under laminar conditions) in a pipe is A. Parabolic B. Flat C. Flat near the wall and parabolic in the middle D. Parabolic near …

WebFor laminar flow of a Bingham plastic in a horizontal pipe of radius R, the velocity profile is given as u (r) = (ΔP/4? L) (r2 − R2) + (?y /? ) (r − R), where ΔP/L is the constant pressure drop along the pipe per unit length, ? is the dynamic viscosity, r is the radial distance from the centerline, and ?y is the yield stress of Bingham plastic.
