1. Study of Conservation on Implicit Techniques for Unstructured Finite Volume Navier-Stokes Solvers
ABSTRACT: The work is a study of conservation on linearization techniques of time-marching schemes for the unstructured finite volume Reynolds-averaged Navier-Stokes formulation. The solver used in this work calculates the numerical flux applying an upwind discretization based on the flux vector splitting scheme. This numerical treatment results in a very la

2. Los Programas de Transferencia de Renta Condicionadas como gestión neoliberal de la cuestión social
Neoliberalism continues to demonstrate its incompetence when considering a reasonable standard of social integration. The Programs of Conditional Cash Transfer implemented in Uruguay from the creation of the Ministry of Social Development (Mides) in 2005 were designed with the explicit objective of combating extreme poverty, a direct result of the applicatio

3. A unified discrete-time approach to the state space representation of aeroelastic systems.
In complex flow situations, it is common to use numerical tools to evaluate the aerodynamic unsteady behavior. The present work presents an alternate formulation for the state space representation of aeroelastic systems based on digital control theory that is shown to be effective and accurate for the coupling of numerical solutions with such systems. The ap

4. Incertezas de modelo na análise de torres metálicas treliçadas de linhas de transmissão / Model uncertainties in the transmission lines latticed steel towers analysis
Incertezas de modelo invadem todos os estágios de uma análise de confiabilidade estrutural, desde a determinação das ações e do próprio sistema estrutural, até o processo pelo qual o efeito destas ações é avaliado. Neste trabalho, o enfoque é dado nesse último tópico, mais especificamente na avaliação das incertezas de modelo mecânico em tor

5. Numerical simulation of fluid flow in CFB risers: A turbulence analysis approach
Turbulence parameters are derived from results of numerical simulation of gas-solid flow in circulating fluidized bed (CFB). A two fluid model with constant viscosity is applied considering an Eulerian continuum approach for both phases. An analysis is performed using a direct numerical integration of balance equations without an explicit use of any turbulen
