As a first step in this bold goal, this current paper aims to benchmark three CFD codes from various origins and distinct numerical schemes: Concha [1], elsA [2], ANSYS-FLUENT

As well as the capital-labor conflicts over the production of sanitary equipment, this crisis highlights a reality of the world of labor that is often less considered among the

I have further argued that syntactic raising of the ECMed subject to the matrix clause is optional and when the raising takes place, it is a two-step process: first, it is raised
