Longer time simulation of the unsteady Navier-Stokes equations based on a modified convective formulation
Xu Li, Hongxing Rui
For the discretization of the convective term in the Navier-Stokes equations (NSEs), the commonly used convective formulation (CONV) does not preserve the energy if the divergence…

An EMA-conserving, pressure-robust and Re-semi-robust reconstruction method for the unsteady incompressible Navier-Stokes equations
Xu Li, Hongxing Rui
Proper EMA-balance (E: kinetic energy; M: momentum; A: angular momentum), pressure-robustness and -semi-robustness (: Reynolds number) are three important properties of Nav…
