AXIAL FLOW IN A ROTATIONAL COAXIAL RHEOMETER SYSTEM 1. BINGHAM PLASTIC
A mathematical analysis has been carried out for the axial flow of a Bingham plastic fluid, in the Concentric Cylinder Viscometer which consists of a cylindrical sample holder (the cup) and a cylindrical spindle (the bob) coaxial with the cup. The fluid to be tested flows through the annular gap of the cup and the bob system, sheared by the rotation of the inner cylinder, while the outer cy...
متن کاملOn the numerical simulation of Bingham visco-plastic flow: Old and new results
The main goal of this article is to review various results and methods concerning the numerical simulation of Bingham visco-plastic flow; these results have been obtained from the early 1970s to now. We consider first the case of flow in cylindrical pipes and then flow in multi-dimensional cavities. The methods to be discussed include classical ones relying on regularization, (kind of) Lagrange...

متن کاملA Computational study of Bingham plastic flow of Blood through an artery by multiple stenoses and post dilatation
The present paper deals with fully developed one dimensional Bingham plastic flow of blood through a small artery having multiple stenoses and post-stenotic dilatation. We have determined the resistanceto flow -ratio for yield stresses 0, .02, .04 n/m, blood viscosities 0.00345, 0.004, 0.00455 Pa.s and fluxes 1, 10, 100. The resistanceto flow moves nearer to unity as yield stress increases and ...
متن کاملSolution of the square lid-driven cavity flow of a Bingham plastic using the finite volume method
We investigate the performance of the finite volume method in solving viscoplastic flows. The creeping square lid-driven cavity flow of a Bingham plastic is chosen as the test case and the constitutive equation is regularised as proposed by Papanastasiou [J. Rheology 31 (1987) 385-404]. It is shown that the convergence rate of the standard SIMPLE pressure-correction algorithm, which is used to ...
