ABSTRACT=Blowing air at the end of the airport runway can accelerate the decay of the near-ground aircraft wake vortex, thereby reducing the negative impact of the vortex on the following aircraft. However, for different blowing parameters, the benefits of accelerating wake dissipation are not the same, so it is necessary to set appropriate parameters in order to obtain better acceleration results. Because of the high cost of traditional optimization methods, this research uses Kriging surrogate model to optimize the blowing parameters. The results show that the current optimization algorithm can deal with the global optimization problem well.After obtaining 205 sample points, the response surface model of blowing parameters-blowing yield is established accurately. A relatively optimal parameter setting range is given, and numerical simulation shows that the current parameter setting can obtain a better benefit of accelerated vortex * *Corresponding author.
