Bingham plastic

[′biŋ·əm ‚plas·tik]
(fluid mechanics)
A non-Newtonian fluid exhibiting a yield stress which must be exceeded before flow starts; thereafter the rate of shear versus shear stress curve is linear.

[18] solved Bingham fluids by using the MRT model, but the free surface is not considered in their model.
Therefore, the material can be modeled as a Bingham fluid to predict the final shape.
Starting with the pioneering works by Mosolov and Miasnikov [6] and Duvaut and Lions [7], a large number of mathematicians have worked on the theoretical analysis of Bingham fluids and other similar viscoplastic media (see [8-23] and the references therein).

Free surface profiles and flow field patterns of dip coating with Newtonian and Bingham fluids were analyzed by Hurez and Tanguy [18], with the purpose of finding the location of the free surface and investigating flow characteristics at equilibrium.
Numerical results exhibit robustness and scalability of the solver with respect to the mesh size, demonstrating that the proposed method can be used for the accurate simulation of non-regularized Bingham fluids. A complete convergence analysis of AMLI-preconditioned ABF is fairly complex (stemming from the fact that this is an indefinite saddle-point problem) and is left to future work.
The combination of regularized and non-regularized models presented here specifically for the solution of Bingham fluids is a novel contribution of the present paper.
For the Bingham fluids, the effective viscosity [[mu].sub.e] can be defined as follows:
According to the description of the Bingham rheological model, the TBAB CHS, including types A and B, is verified as Bingham fluid in the range of 0 [less than or equal to] [chi] [less than or equal to] 22.2% and 0 [less than or equal to] [chi] [less than or equal to] 25.0%, respectively.
Concrete and mortar are generally accepted to be Bingham fluids [6].
The present study deals with some of these issues and describes and discusses theoretical grout flow models for predicting flow into plane-parallel fractures of candidate cement grout materials that behave as Bingham fluids under static pressure and as Newton liquids under oscillatory pressure.
