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 کاملAerodynamic Noise Computation of the Flow Field around NACA 0012 Airfoil Using Large Eddy Simulation and Acoustic Analogy
The current study presents the results of the aerodynamic noise prediction of the flow field around a NACA 0012 airfoil at a chord-based Reynolds number of 100,000 and at 8.4 degree angle of attack. An incompressible Large Eddy Simulation (LES) turbulence model is applied to obtain the instantaneous turbulent flow field. The noise prediction is performed by the Ffowcs Williams and Hawkings (FW-...
متن کاملNumerical Simulation of Flow over an Airfoil with a Cavity
Two-dimensional direct numerical simulation of the flow over a NACA0018 airfoil with a cavity is presented. The lowReynolds number simulations are validated bymeans of flow visualizations carried out in awater channel. From the simulations, it follows that there are twomain regimes of flow inside the cavity. Depending on the angle of attack, the first or the second shear-layer mode (Rossiter to...
متن کاملOptimal Control of Unsteady Stokes Flow around an Airfoil and the Sensor/actuator Placement Problem
The task of choosing good sensor and actuator locations to control a distributed system can result in search spaces which grow combinatorially. We propose to apply an initial effectiveness filter based on distributed LQR optimal control which can be computed at polynomial cost. This thought experiment, applied to the NACA 0015 airfoil in an unsteady Stokes flow regime, shows that a disturbance ...
