Non-modal stability in Hagen-Poiseuille flow of a Bingham fluid [PDF]
, 2014 Linear stability in Hagen-Poiseuille flow of a Bingham fluid is considered. Bingham fluid exhibits a yield stress in addition to a plastic viscosity. A Bingham number B, which describes the ratio of yield and viscous stresses, is used to characterize the

Stability of concentrated suspensions under Couette and Poiseuille flow [PDF]
, 2018 The stability of two-dimensional Poiseuille flow and plane Couette flow for concentrated suspensions is investigated. Linear stability analysis of the two-phase flow model for both flow geometries shows the existence of a convectively driven instability ...

Nonmodal stability in Hagen-Poiseuille flow of a shear thinning fluid [PDF]
, 2012 Linear stability in Hagen-Poiseuille flow of a shear-thinning fluid is considered. The non-Newtonian viscosity is described by the Carreau rheological law.

Eigenvalue enclosures and exclosures for non-self-adjoint problems in hydrodynamics [PDF]
, 2010 In this paper we present computer-assisted proofs of a number of results in theoretical fluid dynamics and in quantum mechanics. An algorithm based on interval arithmetic yields provably correct eigenvalue enclosures and exclosures for non-self-adjoint ...

Basic Flows of Generalized Second Grade Fluids Based on a Sisko Model
International Journal of Applied Mechanics and Engineering, 2017 The present investigation is concerned with basic flows of generalized second grade fluids based on a Sisko fluid. After formulation of the general equations of motion three simple flows of viscoplastic fluids of a Sisko type or fluids similar to them ...

Exact solutions for some unsteady flows of a couple stress fluid between parallel plates
Ain Shams Engineering Journal, 2018 Exact solutions for three fundamental unsteady flows of an incompressible couple stress fluid between two parallel plates, namely, Couette, generalized Couette and Poiseuille flows, are obtained. Analytical solutions of the corresponding initial-boundary

Hagen-Poiseuille Flow in a Quarter-Elliptic Tube
Fluids, 2023 We present a rare exact solution of the Navier–Stokes equations for the Hagen–Poiseuille flow through a quarter-elliptic tube. Utilizing the separation of variables method, we derive the solution and report expressions for both the volumetric flow rate ...

Simultaneous Image Registration and Monocular Volumetric Reconstruction of a fluid flow [PDF]
, 2011 We propose to combine image registration and volumetric reconstruction from a monocular video of a draining off Hele-Shaw cell filled with water. A Hele-Shaw cell is a tank whose depth is small (e.g. 1 mm) compared to the other dimensions (e.g.
