High fidelity numerical simulation of airfoil thickness and kinematics effects on flapping airfoil propulsion
High-fidelity numerical simulations with the spectral difference (SD) method are carried out to investigate the unsteady flow over a series of oscillating NACA 4-digit airfoils. Airfoil thickness and kinematics effects on the flapping airfoil propulsion are highlighted. It is confirmed that the aerodynamic performance of airfoils with different thickness can be very different under the same kin...
متن کاملNumerical Simulation of Flow Past Oscillating Airfoil Using Oscillation of Flow Boundary Condition
The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the simulation of flowfield around an oscillating airfoil, this unsteady flow is solved on a fixed g...
متن کاملNumerical Simulations of Natural and Actuated Flow over a 3-D, Low-Aspect-Ratio Airfoil
Numerical simulations of the unsteady flow over a low-aspect-ratio, low Reynolds number semi-circular planform wing are performed using Lattice Boltzmann method. The simulations exactly match the flow conditions and the detailed geometry from previous wind-tunnel experiments, including the flow actuators installed internally along the leading edge of the wing. To reproduce the pulsed-blowing ac...
متن کاملNumerical Simulation of Flow over an Airfoil with a Cavity
Two-dimensional direct numerical simulation of the flow over a NACA0018 airfoil with a cavity is presented. The lowReynolds number simulations are validated bymeans of flow visualizations carried out in awater channel. From the simulations, it follows that there are twomain regimes of flow inside the cavity. Depending on the angle of attack, the first or the second shear-layer mode (Rossiter to...
متن کاملNumerical study of flapping filaments in a uniform fluid flow
The coupled dynamics of multiple flexible filaments (also called monodimensional flags) flapping in a uniform fluid flow is studied numerically for the cases of a side-by-side arrangement, and an in-line configuration. The modal behaviour and hydrodynamical properties of the sets of filaments are studied using a Lattice Boltzmann Immersed Boundary method. The fluid momentum equations are solved...
