2-D Modeling of hyperconcentrated fluid flow in curvilinear coordinates: dam break study

Applied Water Science
The hyperconcentrated fluid flow occurs as a result of heavy rainfall, during which a large amount of sediments from the upstream basin is washed away and suddenly increases the flow concentration of the alluvial channels.

Unsteady Non-Newtonian Solver on Unstructured Grid for the Simulation of Blood Flow

Advances in Mechanical Engineering, 2013
Blood is in fact a suspension of different cells with yield stress, shear thinning, and viscoelastic properties, which can be represented by different non-Newtonian models.

Examining laminar, non-stationary viscoelastic fluid flow between two parallel planes [PDF]

BIO Web of Conferences
The generalized Maxwell model is used to handle problems involving the unsteady flow of a viscoelastic fluid in a flat channel under the effect of a constant pressure gradient.

(In)finiteness of Spherically Symmetric Static Perfect Fluids

, 2002
This work is concerned with the finiteness problem for static, spherically symmetric perfect fluids in both Newtonian Gravity and General Relativity. We derive criteria on the barotropic equation of state guaranteeing that the corresponding perfect fluid

Analytical and Computational Modeling of Relaxation Times for Non-Newtonian Fluids

Fluids
With the availability of efficient and sophisticated finite element analysis (FEA) and computational fluid dynamics (CFD) tools, engineering designs are becoming more software-driven and simulation-based.

A continuum approach applied to a strongly confined Lennard-Jones fluid [PDF]

, 2010
Results from molecular dynamics simulations are analyzed with a continuum approach. It is shown that for strongly confined fluids the Navier-Stokes equations for incompressible, Newtonian fluids are not applicable over the whole channel.

Numerical Analysis of Non-Newtonian Fluid Effects on the Equilibrium Position of a Suspended Particle and Relative Viscosity in Two-Dimensional Flow

Fluids
A solvent in suspension often has non-Newtonian properties. To date, in order to determine these properties, many constitutive equations have been suggested. In particular, power-law fluid, which describes both dilatant and pseudoplastic fluids, has been

Homotopy Simulation of Non-Newtonian Spriggs Fluid Flow Over a Flat Plate with Oscillating Motion

International Journal of Applied Mechanics and Engineering, 2019
An incompressible flow of a non-Newtonian Spriggs fluid over an unsteady oscillating plate is investigated using the Homotopy Analysis Method (HAM). An analytic solution of sine and cosine oscillations of the plate has been obtained.
