Numerical Simulation of a Pitching Naca 0012 Airfoil
This paper describes the application of the noncommercial CFD-code FLOWer to the problem of a sinusoidally pitching NACA 0012 airfoil with high amplitude and reduced frequency under incompressible flow conditions. As FLOWer allows the approximate solution of the nonlinear conservation laws governing viscous fluid flow, i. e. the Navier-Stokes equations, a numerical investigation of the unsteady...
متن کاملDirect Numerical Simulation of Flows over an NACA-0012 Airfoil at Low and Moderate Reynolds Numbers
Direct numerical simulations (DNS) of flow over an NACA-0012 airfoil are performed at a low and a moderate Reynolds numbers of Rec=50*10 and 1*10. The angles of attack are 5 and 15 degrees at the low and the moderate Reynolds number cases respectively. The three-dimensional unsteady compressible Navier-Stokes equations are solved using higher order compact schemes. The flow field in the low Rey...
متن کاملInvestigation of NACA 0012 Airfoil Periodic Flows in a Transonic Wind Tunnel
An experimental study of static and dynamic pressure distributions over a NACA 0012 airfoil in the two-dimensional test section 0.8 × 0.4-meter of a transonic wind tunnel is presented. Tests are conducted at freestream Mach numbers from 0.35 to 0.89, and angle of attack between −2.0 and 15, and Reynolds number based on the airfoil chord length of 3.0 million. Tests are performed at boundary-lay...
متن کاملPlateforme d'étiquetage dynamique pour la fouille d'opinion
Social networks mirror public opinion. Thus, they are of great interest for opinion mining and sentiment analysis. In most cases, sentiment is classified according to a polarity criterion or a linear gradation. Is it possible to learn more complex patterns with limited itemsets? In this article, we investigate brand equity. The goal is to analyze how social groups perceive a given brand. Brand ...
متن کاملProfil épidémiologique des hémoglobinopathies: étude transversale descriptive autour du cas index
Les hémoglobinopathies sont des affections constitutionnelles conséquentes à des anomalies des hémoglobines. Elles sont souvent graves dans leurs formes majeures, leur prise en charge est lourde avec un grand impact psycho-social sur les patients et leur famille. Classées parmi les maladies rares, elles sont encore insuffisamment connues des professionnels de santé. Cette méconnaissance est à l...
