Abstract
In this study, we simulate blood flow in complex geometries obtained by digital subtraction angiography (DSA) images. We represent the flow domain by a set of irregularly distributed nodes or uniform Cartesian embedded grid, and we numerically solve the non-stationary Navier–Stokes (N-S) equations, in their velocity–vorticity formulation, by using a meshless point collocation method. The spatial derivatives are computed with the discretization corrected particle strength exchange (DC PSE) method, a recently developed meshless interpolation method. For the transient term a fourth order Runge–Kutta time integration scheme is used.
