The constitutive models most often used to describe a viscoplastic fluid are the Bingham con-stitutive model [1] or the slightly more general Herschel-Bulkley constitutive model (2.8)-(2.9). The deformation and flow behavior of viscoplastic fluids can be realistically represented with the Herschel-Bulkley constitutive equation, which we have utilized as the basis for the development Thixotropic elasto-viscoplastic model for structured fluids P. R. de Souza Mendes, Soft Matter , 2011, 7 , 2471 DOI: 10.1039/C0SM01021A Here, analytical solutions are developed for the constant‐speed squeezing flow of viscoplastic fluids. It is assumed that the fluid is purely viscous, and hence viscoelastic effects unimportant. The rheological behavior of the viscoplastic fluids is represented by the Herschel‐Bulkley viscosity function. Regarding the viscoplastic fluid flow past triple cylinders (as mentioned in the Introduction), to the best of the authors’ knowledge, this is the first study that examines the interaction between the cylinders and the unyielded regions around the objects in the presence of the viscoplastic fluid.

The archetypal feature of a viscoplastic fluid is its yield stress: If the material is not sufficiently stressed, it behaves like a solid, but once the yield stress is exceeded, the material flows like a fluid. Viscoplastic fluid mixing in a rotating tank.

An experimental study was conducted to measure the settling velocity of spherical particles in viscoplastic fluids. Using a mechanistic model based on the balance of the forces acting on the settling particle and detailed statistical analyses of the experimental results, a generalized model for predicting settling velocity of spherical particles in viscoplastic fluids was developed.

In particular, the investigation focuses on the morphological aspects of drops after inertial spreading. While … In Stokes flow of a particle settling within a bath of viscoplastic fluid, a critical resistive force must be overcome in order for the particle to move. This leads to a critical ratio of the buoyancy stress to the yield stress: the critical yield number. sion for viscoplastic fluids was derived by Pleiner.

Consequently, the theory of the fluid mechanics of such materials has applications in wide array of different fields, ranging from the oil, gas and chemical industries, to food processing and to geophysical fluid dynamics. Viscoplastic flow behaviour was first modelled by Eugene Bingham in 1922.
