Augmenting a Physics-Informed Neural Network for the 2D Burgers Equation by Addition of Solution Data Points
Marlon Sproesser Mathias, Wesley Pereira de Almeida, Marcel Rodrigues de Barros +9
We implement a Physics-Informed Neural Network (PINN) for solving the two-dimensional Burgers equations. This type of model can be trained with no previous knowledge of the solutio…
A Physics-Informed Neural Network to Model Port Channels
Marlon S. Mathias, Marcel R. de Barros, Jefferson F. Coelho +8
We describe a Physics-Informed Neural Network (PINN) that simulates the flow induced by the astronomical tide in a synthetic port channel, with dimensions based on the Santos - São…
Optimal computational parameters for maximum accuracy and minimum cost of Arnoldi-based time-stepping methods for flow global stability analysis
Marlon Sproesser Mathias, Marcello Augusto Faraco de Medeiros
Global instability analysis of flows is often performed via time-stepping methods, based on the Arnoldi algorithm. When setting up these methods, several computational parameters m…
Enhancing Oceanic Variables Forecast in the Santos Channel by Estimating Model Error with Random Forests
Felipe M. Moreno, Caio F. D. Netto, Marcel R. de Barros +9
In this work we improve forecasting of Sea Surface Height (SSH) and current velocity (speed and direction) in oceanic scenarios. We do so by resorting to Random Forests so as to pr…
Modeling Oceanic Variables with Dynamic Graph Neural Networks
Caio F. D. Netto, Marcel R. de Barros, Jefferson F. Coelho +8
Researchers typically resort to numerical methods to understand and predict ocean dynamics, a key task in mastering environmental phenomena. Such methods may not be suitable in sce…
The effect of Mach number on open cavity flows with thick or thin incoming boundary layers
Marlon Sproesser Mathias, Marcello Augusto Faraco de Medeiros
The Rossiter modes of an open cavity were studied using global linear analysis and nonlinear numerical simulations. The length over depth ratio was two and the Reynolds numbers bas…
