1. Numerical Study of Wall Ventilation in a Transonic Wind Tunnel
ABSTRACT: Transonic wind tunnels (TWT) are sophisticated tools for the investigations of flows with Mach numbers of order one. The most characteristic feature of a facility such as this is, for sure, the openings in the walls of the test section. The openings in the walls permit the proper relief effect, and this, on the other hand, makes possible the experi

2. Advanced turbulence modelling for complex aerospace applications.
The objective of the present research work consists in studying complex aerodynamic flows about typical aerospace configuration, in which turbulence effects play a fundamental role. Such study is performed with an available computational tool that is being developed at CTA/IAE. This is a finite-volume code for unstructured 3-D meshes that solves the compress

3. Unsteady aerodynamic forces for aeroelastic analysis of two-dimensional lifting surfaces
The present work is part of an effort for developing a methodology for the aeroelastic analysis of two-dimensional lifting surfaces using an unsteady, Euler-based, CFD tool for the calculation of the aerodynamic operator. The CFD tool solves the flow problem with the finite-volume method applied to an unstructured grid context. The proposed methodology is ba

4. A study on correction methods for aeroelastic analysis in transonic flow.
The work presents a study of correction techniques to compute unsteady transonic pressure distributions and aeroelastic stability in this flow regime. The methodologies herein investigated are based on corrections of pressure distributions by the weighting of the lifting surface self-induced downwash, resulting from aeroelastic structural displacements or pr

5. Numerical solution of the Euler equations for representation of transonic flows over airfoils / Solução numérica das equações de Euler para representação do escoamento transônico em aerofólios
The study of aerodynamic modeling methods for the transonic flow regime is of great importance in aeronautical engineering. Major challenge on the treatment of those flows is on their nonlinear features due to compressibility effects and shock waves (appearance). Such nonlinear effects present a strong influence on aerodynamic performance, as well as they ar
