WebApr 11, 2024 · Laminar free convective heat transfer to power-law and Bingham plastic fluids from a vertical surface has been studied numerically. New extensive results for streamlines, isotherms, local and surface-averaged Nusselt number presented herein embrace the following ranges of conditions: 0.2 ≤ n ≤ 1; 1 ≤ Pr PL ≤ 100; 10 ≤ Gr PL ≤ 10 … WebIn contrast to a Bingham fluid, a pseudoplastic fluid is a fluid that increases viscosity as force is applied. A typical example is a suspension of cornstarch in water with a concentration of one to one. This cornstarch behaves like water when no force is applied; however, it is solidified as force is applied.

WebSep 2, 2024 · Concept of Bingham Bodies. A Bingham plastic is a substance that is known as viscoplastic. They behave like a rigid body under low stress but flow like fluid under high loads. Its mathematical form was invented by Eugene C. Bingham. It is therefore named after him. It is generally used in drilling engineering and slurry handling. WebDec 12, 2024 · Pseudoplastic flow exhibits the behavior of both Newtonian flow and plastic flow. Newtonian flow of fluids describe the property of the viscous stress that arises from the fluid’s flow at every point that is linearly correlated to the local strain rate. CONTENTS. 1.

WebJun 15, 2024 · Bingham fluid, which is a non-Newtonian fluid which is most frequently used for the study of concrete. Note: Non-Newtonian fluid is the fluid that does not obey newton’s law of viscosity. In Bingham model a single -point test like workability only gives a single value. But to form a line we need minimum of two points.
