Title: A parallel simulation algorithm of three dimensional atmospheric turbulence
Abstract: Flight performance is effected by dynamic changes of the atmosphere.To improve the resolution and real-time property of atmospheric model in synthetic natural environment,a three-dimension discrete grid field of turbulence was generated based on Dryden model with spatial correlation function.parallel simulation of the three-dimension atmospheric turbulence was presented,which adopted the method of matrix decomposition.The speedup of the parallel computing was analyzed by experiment on cluster,and the validity was tested by correlation analysis method.It provides a solution of fast-generated dynamic atmospheric model,and has some practical effect to increase the resolution of atmospheric model in synthetic natural environment.
