A possible strategy for the reduction of aeroacoustic noise generated by turbulence interacting with a wing profile, also referred to as leading-edge noise, is represented implementation porous medium in structure airfoil. However, physical mechanisms involved this mitigation technique remain unclear. The present work aims at elucidating these phenomena and particularly how porosity affects incoming characteristics immediate vicinity surface. NACA-0024 profile equipped melamine foam has been...
Large-eddy simulations are performed to investigate turbulent flows through 90° pipe bends that feature unsteady flow separation, unstable shear layers, and an oscillation of the Dean vortices. Single with curvature radii one- three-pipe diameters considered at Reynolds number range 5000–27 000. The numerically computed distributions time-averaged velocities, stress components, power spectra velocities validated by comparison particle image velocimetry measurements. overall forces onto walls...
Owls are known for their silent flight. Even though there is some information available on the mechanisms that lead to a reduction of noise emission, neither morphological basis, nor biological owl's flight known. Therefore, we have initiated systematic analysis wing morphology in both specialist, barn owl, and generalist, pigeon. This report presents comparison between feathers owl pigeon emphasise specific characteristics macroscopic microscopic level. An understanding features underlying...
To support Lee's buffet mechanism model [B. H. K. Lee, “Self-sustained shock oscillations on airfoils at transonic speeds,” Prog. Aerosp. Sci. 37, 147–196 (2001)10.1016/S0376-0421(01)00003-3], the sound wave propagation in flow field outside separation of a Mach number M∞ = 0.73 and an angle attack α 3.5° over DRA 2303 supercritical airfoil is determined using high-speed particle-image velocimetry. Furthermore, influenced by artificial source which evidently changes oscillation properties....
Although low-disturbance ("quiet") hypersonic wind tunnels are believed to provide more reliable extrapolation of boundary-layer transition behavior from ground flight, the presently available quiet facilities limited Mach 6, moderate Reynolds numbers, low freestream enthalpy, and subscale models. As a result, only conventional ("noisy") can reproduce both numbers enthalpies flight configurations must therefore be used for vehicle test evaluation involving high number, larger This paper...
The Air Quality Model Evaluation International Initiative (AQMEII) has now reached its second phase which is dedicated to the evaluation of online coupled chemistry-meteorology models. Sixteen modeling groups from Europe and five North America have run regional air quality models simulate year 2010 over one European American domain. MACC re-analysis been used as chemical initial (IC) boundary conditions (BC) by all participating in AQMEII-2. aim present work evaluate along with against a set...
