ON EFFECTIVE COMBINATION OF HEURISTIC ALGORITHMS AND DYNAMIC MESHES IN CFD APPLICATIONS

摘要

In the study presented, dynamic mesh method applications on Heuristic Algorithms are investigated in the design of wing geometry. In our application dynamic mesh technique is implemented on a real coded genetic algorithm to demonstrate gain in computational time as well as in higher performance for optimized parameters. Since the differences developed at each step in geometries of new members are not much, it is possible to use dynamic mesh methods for new members. In this work, because the population members are obtained by modifying the pervious ones, each member is considered as one step of geometry-change of a deforming body, for example a wing inflating, deflating or cambering. Obviously the strategy applied here can be used for any slowly deforming complex geometries, as long as an effective combination of the genetic algorithm and dynamic mesh be succeeded.
