摘　　要：The fractal dimensions of turbulent round jets in steady crossflow has been analyzed by using planar laser-induced fluorescence (PLIF) method. The relation between the fractal dimension and the momentum ratio, the variation of the fractal dimension with the elevation of jet and the dilution have been investigated. The comparison of the fractal characteristics between the multiple jets and the signal jet has been carried out.The fractal dimensions of turbulent round jets in steady crossflow has been analyzed by using planar laser-induced fluorescence (PLIF) method.
