In this paper, we compare the solutions for the Navier-Stokes equations with moderate and very high Reynolds numbers obtained using a Fixed Point Iterative Method with those obtained using COMSOL Multiphysics. Despite the advantages of COMSOL, we wan

Abstract In this article, an incompressible, two‐dimensional (2D), time‐dependent Newtonian fluid flow in a square cavity is simulated using finite difference method and alternating direction implicit technique. Navier‐Stokes equations are solv

We present a strong form, meshless point collocation explicit solver for the numerical solution of the transient, incompressible, viscous Navier-Stokes (N-S) equations in two dimensions. We numerically solve the governing flow equations in their stre

We develop a Proper Orthogonal Decomposition (POD)-Galerkin based Reduced Order Model (ROM) for the efficient numerical simulation of the parametric Navier-Stokes equations in the stream function-vorticity formulation. Unlike previous works, we choos

In this report the regular finite differences method (FDM) and a least-squares radial basis function-generated finite differences method (RBF-FD-LS) is used to solve the two-dimensional incompressible Navier-Stokes equations for the lid driven cavity

In this paper we study a viscous fluid flow over a V-shaped body for a range of Reynold's number from Re = 5 up to Re = 500. We solved the unsteady Naveir-stokes equations in the stream function - vorticity formulation. The irregular physical domain

Suitability of finite difference method and finite volume method for computation of incompressible non newtonian flow is analyzed. In addition, accuracy of numerical results depending of mesh size is assessed. Both methods are tested for driven cavit

This study aims to provide insight about how the hemodynamic factors change with artery curvature for a developing aneurysm during a cardiac cycle. The aneurysm is investigated in terms of the vortical structure and the shear stress along the curved
