15 صفحه اولComputational algorithms for aerodynamic analysis and design *
While the applications of computational fluid dynamics are pervasive throughout applied science and engineering, ranging from astrophysics to the design of cooling systems for semi-conductors, its role in aircraft design is crucial to an unusual extent, because of the narrow margins within which aircraft can operate efficiently. If computational aerodynamics is to be truly effective in the desi...
متن کاملA three-dimensional computational study of the aerodynamic mechanisms of insect flight.
A finite element flow solver was employed to compute unsteady flow past a three-dimensional Drosophila wing undergoing flapping motion. The computed thrust and drag forces agreed well with results from a previous experimental study. A grid-refinement study was performed to validate the computational results, and a grid-independent solution was achieved. The effect of phasing between the transla...
متن کاملA computational study of the aerodynamic forces and power requirements of dragonfly (Aeschna juncea) hovering.
Aerodynamic force generation and mechanical power requirements of a dragonfly (Aeschna juncea) in hovering flight are studied. The method of numerically solving the Navier-Stokes equations in moving overset grids is used. When the midstroke angles of attack in the downstroke and the upstroke are set to 52 degrees and 8 degrees, respectively (these values are close to those observed), the mean v...
متن کاملA computational study of the aerodynamic performance of a dragonfly wing section in gliding flight.
A comprehensive computational fluid-dynamics-based study of a pleated wing section based on the wing of Aeshna cyanea has been performed at ultra-low Reynolds numbers corresponding to the gliding flight of these dragonflies. In addition to the pleated wing, simulations have also been carried out for its smoothed counterpart (called the 'profiled' airfoil) and a flat plate in order to better und...
