Abstract The wake steering control in wind farms has gained significant attention the last years. This strategy shown promise to reduce energy losses due effects and increase production a farm. However, conditions are variable farms, measurements uncertain what should be considered design of strategies. paper proposes using probabilistic learning on manifold (PLoM), which can viewed as supervised machine method, enable optimization under uncertainty. expected power generation is estimated...
Abstract This study investigates the potential of Ocean Thermal Energy Conversion (OTEC) technology in Potiguar Basin, that is part Equatorial Margin Brazilian coastline. OTEC based on Rankine thermodynamic cycle, which uses temperature difference between ocean’s surface and deep waters to generate electricity. The methodology employed this development computer algorithms for processing results from a three-dimensional global numerical model. Data situ Argo was used correlate with HYCOM,...
In the present paper, we propose an approach based on probabilistic learning for uncertainty quantification of water-flooding processes in oil reservoir simulations, considering geological and economic uncertainties multiple quantities interest (QoIs). We employ manifolds (PLoM) method, which has achieved success many different applications. This methodology enables construction surrogate models to cope with expensive computational costs using high-fidelity simulators. It also allows...
In this work, numerical solutions of the two-dimensional Navier-Stokes and Euler equations using explicit MacCormack method on multi-block structured mesh are presented for steady state unsteady compressible fluid flows. The technique generalized coordinate system used to develop a solver which can be applied large range flow problems complex geometries without modifying governing method. Besides that is based finite difference approach coordinates introduced allow application boundary...

<title>Abstract</title> Despite significant progress in floating offshore wind turbine (FOWT) technology , there are still several challenges, including the design of a cost-effective system. Considerable research has been dedicated to optimizing platform geometry, layout, dimensions, and weight over past few years, with some focusing on semisubmersible platforms, where steel is often used for both tower. However, concrete FOWTs may be more reduce carbon footprint. Other areas requiring...
O estudo e a análise numérica das equações de Navier-Stokes para escoamentos compressíveis em geometrias bidimensionais são grande importância, pois estas representam fenômenos envolvendo altas baixas velocidades. A discretização implementação coordenadas generalizadas (Ç, rJ) via métodos numéricos, geradas métricas que relacionam o sistema físico com computacional,gerando uma malha estruturada coincidente fronteira do domínio [1],[2]. Existem vários geração malhas, entretanto método baseado...
Abstract The present paper aims at investigating the impact of wake effect on levelized cost energy (LCOE) a wind farm located offshore Rio de Janeiro. study is performed using reference 15-megawatt (MW) turbine International Energy Agency (IEA). defined over square area, where initially 5 × 15MW turbines are placed uniformly this area. To investigate LCOE, buildable area varied systematically from (4 3D) to 15D) 15D), D rotor diameter. perform layout optimization, symmetrical optimization...
