Exponential stability of an incompressible non-Newtonian fluid with delay [PDF]

, 2018
The existence and uniqueness of stationary solutions to an incompressible non-Newtonian fluid are first established. The exponential stability of steady-state solutions is then analyzed by means of four different approaches.

Application of QLM-Rational Legendre collocation method towards Eyring-Powell fluid model

Nonlinear Engineering, 2019
In this paper, a spectral method based on the rational Legendre functions is discussed to approximate the solution of the boundary layer flow of an Eyring-Powell non-Newtonian fluid over a stretching sheet.

On building machine learning models for medical dataset with correlated features

Computational and Mathematical Biophysics
This work builds machine learning models for the dataset generated using a numerical model developed on an idealized human artery. The model has been constructed accounting for varying blood characteristics as it flows through arteries with variable ...

Stochastic shear thickening fluids: Strong convergence of the Galerkin approximation and the energy equality

, 2012
We consider a stochastic partial differential equation (SPDE) which describes the velocity field of a viscous, incompressible non-Newtonian fluid subject to a random force. Here, the extra stress tensor of the fluid is given by a polynomial of degree p-1

A Multigrid Optimization Algorithm for the Numerical Solution of Quasilinear Variational Inequalities Involving the $p$-Laplacian

, 2017
In this paper we propose a multigrid optimization algorithm (MG/OPT) for the numerical solution of a class of quasilinear variational inequalities of the second kind. This approach is enabled by the fact that the solution of the variational inequality is

On the existence of classical solution to the steady flows of generalized Newtonian fluid with concentration dependent power-law index

, 2018
Steady flows of an incompressible homogeneous chemically reacting fluid are described by a coupled system, consisting of the generalized Navier--Stokes equations and convection - diffusion equation with diffusivity dependent on the concentration and the ...

Augmenting heart disease prediction with explainable AI: A study of classification models

Computational and Mathematical Biophysics
Although heart disease stands as a prominent contributor to worldwide deaths, not all individuals affected by it ultimately fall prey to its effects. Timely diagnosis and effective treatment can offer those with heart conditions a high-quality life in ...

Global generalized solutions for Maxwell-alpha and Euler-alpha equations

, 2011
We study initial-boundary value problems for the Lagrangian averaged alpha models for the equations of motion for the corotational Maxwell and inviscid fluids in 2D and 3D. We show existence of (global in time) dissipative solutions to these problems. We
