Application of K-means for Identification of Multiphase Flows Based on Computational Fluid Dynamics

Patrick Souza Lima, Leonardo Santos de Souza, Leizer Schnitman, Idelfonso B. R. Nogueira

This study explores multiphase flow dynamics with a focus on the annular flow regime using Computational Fluid Dynamics (CFD) simulations. The methodology included defining the physical model, generating the computational mesh, and analyzing flow patterns. The Volume of Fluid (VOF) model captured …

Asteroidea (Echinodermata) from Uruguay (SW Atlantic): an annotated checklist and zoogeographic considerations

Pablo E. Penchaszadeh, Leonardo Ortega, Rosario Quintero, Alvar Carranza et autres

The diversity of Asteroidea from the Southwestern Atlantic between 30°S and 40°S (southern Brazil, Uruguay and northern Argentinean waters) has been thoroughly studied since the late 19thcentury. However, like many other benthic metazoans, the existing knowledge of species particularly reported from Uruguayan …

Melanella martarum sp. nov. (Gastropoda: Eulimidae): the first parasitic deep-sea snail reported for the Salas & Gomez Ridge

Leonardo Santos de Souza, Cynthia M. Asorey, Javier Sellanes

Eulimidae is a highly diverse family of gastropods that are often parasites of echinoderms. They are cosmopolitan and live from the intertidal to great depths. Despite its wide geographic and bathymetric distribution, no species of Eulimidae have been reported for the Salas …

Taxonomic review of Aclis Lóven, 1846 (Gastropoda, Eulimidae) from Brazil with notes on other congeners from the western Atlantic and Saint Helena

Leonardo Santos de Souza, Alexandre Dias Pimenta

A taxonomic review of Aclis Lóven, 1846 from Brazil led to the discovery of ten species, five of them are new. Before this study, only four species were known from the area. Aclis sarissa Watson, 1881 is revised and reassessed regarding its …

Catálogo Taxonômico da Fauna do Brasil: Setting the baseline knowledge on the animal diversity in Brazil

Walter A. Boeger, Michel P. Valim, Hussam Zaher, José Albertíno Rafael et autres

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of …

How many species of Mollusca are there in Brazil? A collective taxonomic effort to reveal this still unknown diversity

Fabrizio Marcondes Machado, Marcel Sabino Miranda, Rodrigo B. Salvador, Alexandre Dias Pimenta et autres

The expression ‘you need to know to conserve’ is a well-known cliche among biologists. Documenting the richness of a group of organisms is the first step towards understanding biodiversity and preparing efficient conservation plans. In this context, many efforts have been made …

OTIMIZAÇÃO ECONÔMICA EM TEMPO REAL ORIENTADA A DADOS PARA POÇOS DE PETRÓLEO COM INJEÇÃO DE GÁS

Ezequias. S. Matos, Odilon S.L. de Abreu, Taniel S. Franklin, Leonardo Santos de Souza et autres

This work addresses the daily economic optimization problem in gas-lift oil wells. The proposal uses an artificial neural network (ANN) to find the optimal solution with a lower computational cost than one produced with a phenomenological model. However, a first-principle nonlinear model …

A Physics-Informed Neural Networks (PINN) oriented approach to flow metering in oil wells: an ESP lifted oil well system as a case study

Taniel S. Franklin, Leonardo Santos de Souza, Raony M. Fontes, Márcio A.F. Martins

A virtual flow meter (VFM) is an interesting and growing method to replace or support expensive and high-maintenance dependent physical flow rate sensors in oil and gas production systems. This paper presents a new use of Physics-Informed Neural Networks (PINN) as a …
