文摘The fractal dimension of a jet into a crossflow is calculated by means of PLIF (planar laser induced fluorescence) technique and box counting method. The effects of the intersection position, image averaging and threshold setting on the fractal dimension are investigated in detail. Results illustrate that a jet into a crossflow also behaves with the fractal characteristics. Compared with a free axisymmetric jet, the jet into the crossflow has stronger anisotropy, resulting in a fractal dimension varying with the momentum ratio.
