Rod-airfoil 网格
WebRod–airfoil interaction noise is a major concern in several practical industrial and aeronautical applications. In this study, we constructed bio-inspired gradient distributed porous leading edges to reduce rod–airfoil interaction noise. Noise radiations by NACA 0012 airfoils with nonporous aluminum and porous leading edges were experimentally … WebWall-modeled large-eddy simulation of the flow past a rod-airfoil tandem by the Lattice Boltzmann method.

WebThe airfoil is set at zero angle of attack for the simulations. The flow conditions are specified by the Reynolds number (based on the rod diameter), Red = 48 K, and the flow Mach number, M = 0.2. Comparisons with measured data are made for (a) mean and root-mean-squared velocity profiles in the rod and airfoil wakes, (b) velocity spectra in ...
Webof the inflow turbulence. Agrawal and Sharma [18] studied the effect of leading edge serrations on a rod-airfoil configuration using a high-order LES. The serration amplitude and wavelength were 6% and 30% of the airfoil chord length respectively. The serrated airfoil was found to reduce noise mainly at higher frequencies. WebThe experiment setup of rod–airfoil interaction wind tunnel is shown in Figure 1. Figure 2 shows the computational domain. The airfoil, chord length of the airfoil, and rod diameter …
