An analysis of existing and newly derived fast-projection methods for the numerical integration of incompressible Navier–Stokes equations is proposed. Fast-projection methods are based on the explicit time integration of the semi-discretized Navier

A method is proposed for the derivation of new classes of staggered compact derivative and interpolation operators. The algorithm has its roots in an implicit interpolation theory consistent with compact schemes and reduces to the computation of the

The spatial discretization of convective terms in compressible flow equations is studied from an abstract viewpoint, for finite-difference methods and finite-volume type formulations with cell-centered numerical fluxes. General conditions are sought

We analyze the conservation properties of various discretizations of the system of compressible Euler equations for shock-free flows, with special focus on the treatment of the energy equation and on the induced discrete equations for other thermodyn

Despite the current increase in computing power, Direct Numerical Simulations (DNS) of turbulent flows of industrial interest are still out of reach and more efficient algorithms are necessary to obtain accurate results in a satisfactory amount of ti

Numerical discretization of Navier-Stokes equations are widely known to be susceptible to nonlinear numerical instabilities at high values of the Reynolds number, when central non-dissipative schemes are used. One of the possible remedies which have

Introduction The analysis of intracardiac blood flow patterns can significantly contribute to improve the understanding and treatment of cardiovascular disease. In contrast to the substantial literature on the left side of the heart, there is current

Helicity is the scalar product between velocity and vorticity and, just like energy, its integral is an inviscid invariant of the 3D incompressible Navier–Stokes equations, $$\frac{\partial {u}_{i}}{\partial t} + \mathscr {N}_{i}({u}) = -\frac{\par

Nonlinear convective terms pose the most critical issues when a numerical discretization of the Navier–Stokes equations is performed, especially at high Reynolds numbers. They are indeed responsible for a nonlinear instability arising from the ampl
