Computational Analysis of Rheological Secondary Flow in a Pipe-Manifold Containing In-Plane Double Bends

Journal of Applied Fluid Mechanics, 2023
Non-Newtonian fluid flow in pipe bends is inevitable in industrial applications. Previous researchers have extensively explored Newtonian flow through curved ducts. However, the non-Newtonian counterpart gets little attention. We study the turbulent flow

Numerical manifold method modeling of coupled processes in fractured geological media at multiple scales

Journal of Rock Mechanics and Geotechnical Engineering, 2020
The greatest challenges of rigorously modeling coupled hydro-mechanical (HM) processes in fractured geological media at different scales are associated with computational geometry.

Fluid Flow Analysis at Single and Dual Plenum Intake Manifolds to Reduce Pressure Drops Using Computational Approach

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2022
The intake manifold is one of the most important components of an internal combustion engine as it distributes air to each combustion chamber. In certain situations, a restrictor is added at the inlet of the intake manifold.

INVARIANT SPACES OF OSKOLKOV STOCHASTIC LINEAR EQUATIONS ON THE MANIFOLD

Bulletin of the South Ural State University series Mathematics Mechanics Physics, 2021
The Oskolkov equation is obtained from the Oskolkov system of equations describing the dynamics of a viscoelastic fluid, after stopping one of the spatial variables and introducing a stream function.

On the coupling between an ideal fluid and immersed particles [PDF]

, 2012
In this paper we use Lagrange-Poincare reduction to understand the coupling between a fluid and a set of Lagrangian particles that are supposed to simulate it. In particular, we reinterpret the work of Cendra et al. by substituting velocity interpolation

Edge states control droplet break-up in sub-critical extensional flows [PDF]

, 2018
A fluid droplet suspended in an extensional flow of moderate intensity may break into pieces, depending on the amplitude of the initial droplet deformation. In subcritical uniaxial extensional flow the non-breaking base state is linearly stable, implying

Actuation manifold from snapshot data [PDF]

Journal of Fluid Mechanics
We propose a data-driven methodology to learn a low-dimensional manifold of controlled flows. The starting point is resolving snapshot flow data for a representative ensemble of actuations. Key enablers for the actuation manifold are isometric mapping as

Incompressible fluid problems on embedded surfaces: Modeling and variational formulations [PDF]

Interfaces and free boundaries (Print), 2017
Governing equations of motion for a viscous incompressible material surface are derived from the balance laws of continuum mechanics. The surface is treated as a time-dependent smooth orientable manifold of codimension one in an ambient Euclidian space ...

Learning the Latent dynamics of Fluid flows from High-Fidelity Numerical Simulations using Parsimonious Diffusion Maps [PDF]

The Physics of Fluids
We use parsimonious diffusion maps (PDMs) to discover the latent dynamics of high-fidelity Navier–Stokes simulations with a focus on the two-dimensional (2D) fluidic pinball problem.

Integration of D-dimensional 2-factor spaces cosmological models by reducing to the generalized Emden-Fowler equation [PDF]

, 1998
The D-dimensional cosmological model on the manifold $M = R \times M_{1} \times M_{2}$ describing the evolution of 2 Einsteinian factor spaces, $M_1$ and $M_2$, in the presence of multicomponent perfect fluid source is considered. The barotropic equation
