## Abstract This article mainly concerns modeling the stochastic input and its propagation in incompressible NavierβStokes(NβS) flow simulations. The stochastic input is represented spectrally by employing orthogonal polynomial functionals from the Askey scheme as trial basis to represent the rando
A new finite difference method for the discretization of the incompressible Navier -Stokes equations is presented. The scheme is constructed on a staggered-mesh grid system. The convection terms are discretized with a fifth-order-accurate upwind compact difference approximation, the viscous terms ar
