A combined theoretical and experimental investigation is conducted with the objective of evaluating lift aerodynamic admittances an airfoil in various turbulent flow fields. Current approaches concepts are reviewed extended, enabling us to use a strategy measure one-wavenumber admittance field. The key separate spanwise effect from generalized which can be directly determined by one-dimensional spectrum velocity spectrum. With this strategy, values two-dimensional NACA 0015 profile three...
The unsteady lift of a NACA (National Advisory Committee for Aeronautics) 0015 airfoil with harmonic pitching frequency fα encountering periodic streamwise superimposed flow is investigated via wind tunnel test. An extended method predicting the characteristics under incoming various sinusoidal multiple frequencies fu presented and experimentally verified. spectral result experiment confirms existence sum fα+fu difference |fα−fu|, indicating that pitch motion interact as Greenberg's theory....
The flow structure and reattaching characteristic of two tandem rectangular cylinders with aspect ratio being 5:1 have been investigated through wind tunnel experiments three-dimensional large eddy simulation (LES) methods. gap width G between the varies from 2 times D to 20 D, where represents depth cylinders. surface pressure distribution aerodynamic forces each cylinder are obtained via experiments. Two distinct patterns identified increasing LES methods, results presented in good...
Abstract The uniform grid is widely used for the aim of generating approximately homogeneous and isotropic turbulence. Although many previousstudies have investigated influence initial conditions square grids, including Reynolds number, mesh size, bar size,cross-section solidities, on statistical characteristics ofthe turbulence, shape has rarely been studied. Compared to traditional grid, present workinvestigates different shapes (the non-square grid) this change canbe easily achieved based...
