Numerical simulation of transonic flows by a flexible and parallel evolutionary computation

Abstract

In this work we propose a Flexible and Parallel Evolutionary Computation to solve a problem of Aeronautic interest, which is the non-linear full potential flow problem inside a nozzle. As the target to verify a numerical scheme for nodal points is equivalent to minimize a corresponding objective function, our methodology consists in using Evolutionary Algorithms as a numerical simulation method. Moreover, as Parallel Evolutionary Algorithms are demanded for an effective reduction of computation time, an Island or Coarse-Grained Parallel model is considered. The methodology proposed opens the possibility to solve the problem from a more local point of view as domain decomposition and permits to incorporate easily theoretical mathematical foundations of the problem. These are powerful characteristics of the method. © 2009 Springer-Verlag Berlin Heidelberg.
