2. Simulação computacional de dispositivos de mistura em câmara de combustão para gases de carbonização
Resumo O carvão vegetal proveniente de florestas plantadas é uma fonte de energia renovável utilizada na siderurgia do Brasil, todavia, em sua produção há liberação do gás de pirólise, que pode ser considerado um gás com baixo poder calorífico inferior. A sustentabilidade da produção de carvão vegetal tem demandado a queima destes gases, poden

3. Investigation of the effect of nozzle design on rheological bioprinting properties using computational fluid dynamics
ABSTRACT Bioprinting is the utilization of techniques derived from three-dimensional printing to generate complex biological structures which may replace natural tissues or organs. It employs high spatial resolution deposition of different cell types, growth factors and biomaterials. Those together form bioinks, which are the bioprinting inputs, analogously

6. One-Stage Power Turbine Preliminary Design and Analysis
ABSTRACT: Design and development of gas turbine components are a complex multidisciplinary process. At the beginning of the power class definition and engine configuration it is necessary to conduct a market study. The results obtained are used in gas turbine thermodynamic cycle calculations and analysis in order to define the gas turbine design point. Sever

7. Análise da influência de impelidores laterais no tempo de mistura em tanques de estocagem de diesel com o uso da fluidodinâmica computacional / Analysis of the influence of side-entry mixers on the mixing time in diesel storage vessels using computational fluid dynamics
The homogenization process of hydrocarbons in large scale storage tanks equipped with side-entry impellers plays an important role in a refinery operation, since the quality of the final products depends on the performance of this process. Computational Fluid Dynamics (CFD) is the most viable technique to evaluate and to optimize this process, as experimenta

8. Turbulência em cosmologia: análise de dados simulados e observacionais usando computação de alto desempenho / Turbulence in cosmology: analysis of simulated and observational data using high performance computing
Recent results from the study of the Large-Scale Structure evolution suggest that the process of structure formation may have similarities with the dynamics of a turbulent fluid. The scaling law for the energy distribution in a turbulent fluid shows an inertial range of power -5/3, known as the Kolmogorov s law. This thesis presents an evaluation of the grav

9. Escoamento de fluidos complexos e transporte de partÃculas em geometrias irregulares. / Complex fluid flows and particle transport in irregular geometries.
In this work many types of incompressible laminar Newtonian and Non-Newtonian flows are studied. The interplay of these flows with complex geometries was investigated using computational modeling and numerical solution of the conservation of momentum and mass continuity equations. As a first step, the computational modeling of a network of pores was adopted

10. Parametric analysis of a phenomenological model for vortex-induced motions of monocolumn platforms
Phenomenological models are an important branch in VIV (Vortex-Induced Vibrations) and in VIM (Vortex-Induced Motions) studies to complement the results achieved via CFD (Computational Fluid Dynamics), as the latter tool is not presently a suitable tool for intense use in engineering analysis, due to high computer power requirements. A phenomenological model

11. Emprego da dinâmica dos fluidos computacional na análise do potencial eólico de uma microrregião em Laguna / Use of computational fluid dynamics analysis of wind power potential of a micrositing in Laguna
Através da Dinâmica dos Fluidos Computacional (CFD) verifica-se o comportamento dos ventos na localidade de Laguna, Santa Catarina, sob a influência da topografia acidentada do terreno e efeitos de mudança de rugosidade. Estudos analíticos realizados por Dalmaz (2007), e dados de vento medidos indicam alto potencial eólico na microrregião em estudo e

12. Simulação do escoamento monofásico em um estágio de uma bomba centrífuga utilizando técnicas de fluidodinâmica computacional
Oil production and exploration techniques have evolved in the last decades in order to increase fluid flows and optimize how the required equipment are used. The base functioning of Electric Submersible Pumping (ESP) lift method is the use of an electric downhole motor to move a centrifugal pump and transport the fluids to the surface. The Electric Submersib
