Download or read book Preliminary Study of the Flow on NACA Airfoil for Future Implementation of Active Flow Control written by Jaume Baratech Diaz and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Direct numerical simulations are performed on a NACA 2412 airfoil with an attack angle of 12 degrees and Reynolds numbers between 300 and 35.000. The details of the flow separation, formation and destabilization of the detached shear layer and formation of separation bubbles via flow re- attachment are studied among other phenomena. Results are then post- processed using a data analysis and visualization application. Computational fluid dynamics has proven a handy tool to analyze, characterize and understand the flow over airfoils. A block-structured mesh to run the simulations is created from scratch and presented in this report. The mesh is fully parameterized to save time for future modifications or adaptations. A mesh independence study is undertaken to ensure the mesh does not affect the outcome of the simulations. The lift and drag of the airfoil, as well as the wall shear stress and velocity profiles are calculated and presented in this report. The study is done at varying Re to characterize the transition of the lift and drag coefficients from steady to periodic and then to chaotic. We also present the formation and migration of the separation bubble, which gets closer to the leading edge as the Re increases. Open source software distributed under open public licensing (GPL) is exclusively exploited. The mesh has been created using Gmsh, the simulations have been done with OpenFOAM and the post-processing is done with paraView and grace.

This book was released on 2018-11-06 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind tunnel tests have been conducted on an NACA 2412 airfoil section at Reynolds number of 2.2 x 10(exp 6) and Mach number of 0.13. Detailed measurements of flow fields associated with turbulent boundary layers have been obtained at angles of attack of 12.4 degrees, 14.4 degrees, and 16.4 degrees. Pre- and post-separated velocity and pressure survey results over the airfoil and in the associated wake are presented. Extensive force, pressure, tuft survey, hot-film survey, local skin friction, and boundary layer data are also included. Pressure distributions and separation point locations show good agreement with theory for the two layer angles of attack. Boundary layer displacement thickness, momentum thickness, and shape factor agree well with theory up to the point of separation. There is considerable disparity between extent of flow reversal in the wake as measured by pressure and hot-film probes. The difference is attributed to the intermittent nature of the flow reversal.

This book was released on 2020 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Baseline data were obtained using the upgraded setup. Force and moment data from the load cell were acquired for all cases to obtain aerodynamic loading data. The results showed significantly lower uncertainty levels when compared with the data obtained from the previous setup due to the increased repeatability of the airfoil motion and the direct measurement of aerodynamic forces (which includes the effect of any potential flow three-dimensionality).
