Stress-divergence, Laplacian, and rotational forms of the incompressible Navier--Stokes equations with variable viscosity
Benjamin Cisternas, Douglas R. Q. Pacheco, Felipe Galarce +1
In the Navier--Stokes equations, incompressibility allows rewriting the viscous term in various forms leading to distinct numerical properties and flow descriptions. Furthermore, m…

A Stress-Based Estimator for Pressure and Stress Recovery from Velocity Measurements
Nicolás Barnafi, Benjamín Cisternas, Ernesto Castillo +1
Non-invasive pressure field estimation from velocity measurements is a longstanding engineering problem. We propose, analyze, and test a pressure-recovery method that computes a fu…
