JOURNAL FREE ACCESSAn informal review is presented of the problem of viscous flow in a corner between two intersecting plane rigid boundaries, with particular attention to the behaviour (i) when the stirring that generates the flow is remote and sinusoidal, and (ii) when the stirring is provoked by torsional oscillation of the fluid domain about the line of intersection of the twoboundaries. In each case, weak inertial effects lead to a lag of the response of the fluid behind the forcing mechanism.Conditions determining the existence and evolution of a geometric sequence of eddies in the corner are determined, andthe manner in which the associated streamline pattern reverses during each half-period of the flow is described. Fulldetails may be found in the recent paper of Branicki & Moffatt (2006).View full abstractDownload PDF (720K) -

JOURNAL FREE ACCESSProduction of a glider for the birdman rally contests is effective education for university students. However, designoptimization is difficult so that pre-flight test is hard and a large number of design parameters. In order to optimize thedesign of gliders, flight simulations and genetic optimizations were conducted. The numerical results were in goodagreement with results of the real flight. The population size in the present study was set to 200, the evolution was computedfor 50 generations. The essential design variables of the airplane for the contest were obtained with GA. The simulator wassuggested the optimized model with flexible wing that was not sensitive to flight conditions. The proposed model got thefourth prize and the referee's award of the birdman rally contest 2005. It revealed that the genetic algorithm and flightsimulator are useful to optimize the glider for the birdman rally contest.View full abstractDownload PDF (5581K) -
