International Journal of Modern Physics A, 2002 The classical motion of spinning particles can be described without recourse to particular models or special formalisms, and without employing Grassmann variables or Clifford algebras, but simply by generalizing the usual spinless theory. We only assume the invariance with respect to the Poincaré group; and only requiring the conservation of the ...

Non-Newtonian Endothelial Shear Stress Simulation: Does It Matter? [PDF]
Frontiers in Cardiovascular Medicine, 2022 Patient-specific coronary endothelial shear stress (ESS) calculations using Newtonian and non-Newtonian rheological models were performed to assess whether the common assumption of Newtonian blood behavior offers similar results to a more realistic but ...

Effects of non-Newtonian viscosity on arterial and venous flow and transport [PDF]
Scientific Reports, 2022 It is well known that blood exhibits non-Newtonian viscosity, but it is generally modeled as a Newtonian fluid. However, in situations of low shear rate, the validity of the Newtonian assumption is questionable. In this study, we investigated differences

Numerical modeling of transient non Newtonian thinning fluid flow [PDF]
E3S Web of Conferences, 2023 This study concerns a numerical simulation of transient non-Newtonian fluid flow in a hydraulic pipe resulting from sudden valve closure, commonly known as waterhammer or hydraulic shock. The fluid behaves as a law power model.

Thermo-fluidic significance of non Newtonian fluid with hybrid nanostructures
Case Studies in Thermal Engineering, 2021 The main purpose of this investigation is to analyze the flow and heat transfer behavior of a non Newtonian fluid (Oldroyd B fluid) with hybrid nanostructure subject to externally inclined magnetic field. Cattaneo Christov heat flux model is incorporated

Computational Predictions for Boger Fluids and Circular Contraction Flow under Various Aspect Ratios
Fluids, 2020 This work puts forward a modeling study contrasted against experimental, with focus on abrupt circular contraction flow of two highly-elastic constant shear-viscosity Boger fluids, i.e., a polyacrylamide dissolved in corn-syrup PAA/CS (Fluid-1) and a ...
