The present research investigates the torsional aeroelasticity of the blade of an H-type vertical axis wind turbine subject to stall and post-stall conditions in various Reynolds regimes, which is experienced by the blade in a full revolution. In order to simulate the aerodynamics, a new model based on a combination of the Double Multi Streamtubes (DMST) model and the nonlinear multi-criteria C...

Flapping wing dynamics are of great interest in many research areas, such as bioinspired systems and aircraft aeroelasticity. The findings the present study provide significant insight into importance leading-edge dynamic incidence on propulsive performance flapping airfoils. main objective is to improve characteristics by adding a pitching conventional NACA0012 airfoil at lower spectrum Reynol...

This thesis summarizes investigations performed within design, analysis and experimental evaluation of flexible aircraft structures. Not only the problems, but rather the opportunities related to aeroelasticity are discussed. In the first part of the thesis, different concepts for using active aeroelastic configurations to increase aircraft performance are considered. In particular, one study d...

This paper presents a retrospective on the evolution of modeling and simulation (M&S) as they relate to multiphysics systems. The context space of M&S is defined in terms of number of fields, number of domains, length scale, and computational technologies involved. Representative past and the present efforts on each one of these contexts and some of their combinations are described and their re...

The development of a wind turbine aerodynamics model using a Boundary Integral Equation model (BIEM) is presented. The methodology is valid to study inviscid unsteady flows around three dimensional bodies of arbitrary shape and arbitrarily moving with respect to the incoming flow. The extension of this methodology to study viscosity effects in turbine blade flow at high angle of attack is addre...

An important eld in computational science and engineering is the simulation of the coupled problem of uid ow interacting with a moving structure. A common notation for this is uid-structure interaction (FSI) problems, which include both aeroelasticity and hydroe-lasticity. Herein we give an overview of results obtained within Fluid-Structure Interaction-Structural Design (FSI-SD) a project that...

Nonlinear aeroelasticity of a flapping wing Micro Air Vehicle (MAV) is analyzed in this paper. The geometrically nonlinear deformations are modeled by a nonlinear strain-based beam formulation, coupled with six rigid-body degrees of freedom of the aircraft. Wing flapping kinematics is described using a set of Euler angles. Two types of unsteady aerodynamic formulations are incorporated for load...
