numerical simulation of turbulent flow around an airfoil with blunt trailing edge aerodynamic characteristics modification of this airfoil with base and aerodynamic cavity
this paper is a computational study of the behavior of aerodynamics characteristics of an airfoil with blunt trailing edge and studies the effects aerodynamic performance caused by modifications made to the trailing edge. blunt trailing edge airfoils are of interest in the engineering of large wind turbine blades because they allow for a strong structure with a high aerodynamic lift to struct...
متن کاملLES tests on airfoil trailing edge serration
In the present study, a large number of acoustic simulations are carried out for a low noise airfoil with different Trailing Edge Serrations (TES). The Ffowcs Williams-Hawkings (FWH) acoustic analogy is used for noise prediction at trailing edge. The acoustic solver is running on the platform of our in-house incompressible flow solver EllipSys3D. The flow solution is first obtained from the Lar...
متن کاملNumerical Study of the Aerodynamic Characteristics of a Plunging Rigid Airfoil with Elastic Trailing-Edge Plate
The fluid-structure coupling process of a plunging rigid airfoil with a thin elastic plate attached at the trailing-edge is simulated numerically by using unsteady potential flow source/vortex panel method and the Euler-Bernoulli beam vibration differential equation. The flow characteristics, the unsteady aerodynamic loads, especially the thrust effects of the plunging motion are computed. The ...
متن کاملUnsteady Aerodynamics and Trailing-edge Vortex Sheet of An Airfoil
Unsteady flow models of wings and airfoils have been studied to understand the aerodynamic performance of natural flyers and provide improved maneuverability for micro aerial vehicles (MAVs). Vortex methods have been extensively applied to reduce the dimensionality of these aerodynamic models, based on the proper estimation of the distribution and evolution of the vortices in the wake. In such ...
متن کاملFlow visualization over a thick blunt trailing-edge airfoil with base cavity at low Reynolds numbers using PIV technique
ABSTRACT In this study, the effect of cutting the end of a thick airfoil and adding a cavity on its flow pattern is studied experimentally using PIV technique. First, by cutting 30% chord length of the Riso airfoil, a thick blunt trialing-edge airfoil is generated. The velocity field around the original airfoil and the new airfoil is measured by PIV technique and compared with each other. Then,...
