An outstanding problem in heavy-ion collisions is the inability for models to accurately describe ultra-central experimental flow data, despite that being precisely regime where a hydrodynamic description should be most applicable. We reassess status of this puzzle by computing obtained from multiple recent Bayesian were tuned various observables different collision systems at typical centralit...

This paper intends to evaluate the capacity of self-purification of a river, on the influence of a dynamic wave. Therefore, it was developed a mathematical modeling, where it were used Hydrodynamic Equations, combined with the Advective Diffusive Equation, to describe the behavior of the transport processes in urban rivers. The results showed that the hydraulic parameters play an important game...

Planing vessels usually have low ratios of resistance to weight, so they can move fast on sea surface than the displacement or semi-displacement ships. Access to higher speeds is one of the attractions for designers and users. To achieve higher speeds, reducing the hydrodynamic resistance is a necessity for this class of vessels. In this study, a 3D finite volume approach is used to analyze the...
