Some analytical solutions for flows of Casson fluid with slip boundary conditions

Ain Shams Engineering Journal, 2015
In the present paper, we have studied three fundamental flows namely Couette, Poiseuille and generalized Couette flows of an incompressible Casson fluid between parallel plates using slip boundary conditions.

A direct numerical simulation display of the rotational frame preference of turbulence

AIP Advances, 2023
An elementary observation of a laminar cylindrical Poiseuille–Couette flow profile reveals no distinction in the parabolic streamwise profile, from one without a cross-stream flow, in whatever reference frame the observation is made.

A Study to Investigate the Viscosity Effect on Micro-Confined Fluids Flow in Tight Formations Considering Fluid–Solid Interaction

Frontiers in Earth Science, 2021
Understanding different fluids flow behavior confined in microscales has tremendous significance in the development of tight oil reservoirs. In this article, a novel semiempirical model for different confined fluid flow based on the concept of boundary ...

The importance of mean free path in determining gas flow behaviour [PDF]

, 2010
We investigate whether a power-law form of probability distribution function better describes the free paths of dilute gas molecules in a confined system.

Implementation of micropolar fluids model and hydrodynamic behavior analysis using user-defined function in FLUENT

Advances in Mechanical Engineering, 2020
Micropolar fluids commonly represent the complex fluids with microstructure, for example, animal blood and liquid crystals. To understand the behavior of micropolar fluids and the role of micropolar parameters, different micropolar fluids models were ...

Simulation of Poiseuille flow

Keldysh Institute Preprints, 2021
In this article, plane and space Poiseuille flow was simulate of the lattice Boltzmann method. Because Poiseuille solution is one of the simplest solutions Navier-Stokes equations, it is well for exploring opportunities of lattice Boltzmann method. Simulation flows in plane rectangular and ellipsoidal cylindrical pipes assist to detect advantages and ...

Physics-Informed Neural Network for Solving 2D Steady Incompressible Navier-Stokes Equations: Application to Poiseuille Flow [PDF]

Physics Access
This study explores the application of Physics-Informed Neural Networks (PINNs) to solve the two-dimensional steady incompressible Navier-Stokes equations, focusing on Poiseuille flow in a rectangular channel. Implemented using the DeepXDE library with

Rarefied Poiseuille Flow in a Circular Tube [PDF]

EPJ Web of Conferences, 2019
An isothermal rarefied gas flow through a long circular tube due to longitudinal pressure gradient (a three-dimensional Poiseuille problem) was studied using the linearized Bhatnagar-Gross-Krook model kinetic equation over the whole range of the Knudsen ...

Subcritical transition in channel flows [PDF]

, 2002
Certain laminar flows are known to be linearly stable at all Reynolds numbers, R, although in practice they always become turbulent for sufficiently large R.
