An oil production system is designed to produce in a regime with a steady state flow; however, this steady state condition may not exist. The stability of this system depends on the set of parameters that defines the operational state. A stability solver was developed by the research group at NDF, with many contributions over the[…]
Relatively little is still known about the flow and end effects on cylinders of low aspect ratio. Although this is a simple structure in shape, the flow about it is so complex! Even less is known when one wants to consider passive wake control of these structures under a free water surface (as in a[…]
We are proud to announce the paper in collaboration with Keith J. Roberts, Alexandre Olender, Lucas Franceschini, Robert C. Kirby, Rafael S. Gioria, and Bruno S. Carmo has just been published in Geoscientific Model Development. This paper is a result of our research inside the STMI (Software Technologies for Modelling and Inversion), which is a[…]
In this work “Performance of OpenMP Loop Transformations for the Acoustic Wave Stencil on GPUs”, we evaluate the performance of unroll and tiling, two loop transformations introduced in OpenMP 5.1 and early implemented in Clang 13 for GPUs. Experiments on a common seismic computational kernel demonstrate performance gains on three GPU architectures. Authors are: Jaime Freire[…]
Neste paper são apresentadas simulações de Blade-resolved para o rotor da Turbina Teórica da NREL de 5MW, onde através de uma modelagem de CFD utilizando o OpenFOAM, realizou-se uma comparação entre dois dos mais recomendados modelos de turbulência utilizados na modelagem deste tipo de escoamento, com o objetivo de permitir computar as forças aerodinâmicas atuando[…]
We are happy to share that the paper in collaboration with Bruno Carmo and Daiane Dolci has just been published in Physical Review Fluids. Take a look at the main findings of our paper: We present a method to calculate the sensitivity of the two least stable eigenvalues concerning an external forcing added in a[…]

Recently a paper has been published in the open access journal Wind MDPI, about the environmental impact and life cycle assessment of a deep water floating offshore wind turbine. In the study, we assume the turbine would be used to partly decarbonize an oil & gas production system located at the Brazilian continental shelf (Santos[…]
We are proud to announce that the paper in collaboration with Daiane Dolci, Felipe Silva, Pedro Peixoto, and Ernani Volpe has just been published in Geoscientific Model Development. This paper is a result of our research inside the STMI (Software Technologies for Modelling and Inversion), which is a project of the Research Centre for Greenhouse Gas Innovation (RCGI).[…]
What if you could control the highly disorganised and chaotic 3D turbulent flow that is formed after it goes past a bluff structure and could possibly lead it progressively into a 2D configuration and, for sufficient rotation speeds, eventually eliminate the randomness of the eddies to achieve a smooth flow? The PhD researcher Icaro Carvalho and Professor Gustavo Assi[…]
