Matching the mode evolution diagrams between experiment and wave calculations.
Experimental conditions are expressed as ‘(jet pressure in bar, extreme position Dn, jet temperature in °C)’. Jet mean radius a for each case is determined as a fitting parameter. Legends ‘Exp’ and ‘Cal’ stand for experiment and wave calculation, respectively. (a) Experiment at (1.250, D5, 16.9) and the wave calculation with η1 = 0.095 and a = 13.79 μm. (b) Experiment at (1.402, D5, 16.9) and the wave calculation with η1 = 0.105 and a = 13.71 μm. (c) Experiment at (1.326, D5, 21.4) and the wave calculation with η1 = 0.130 and a = 13.64 μm. (d) Experiment at (1.188, D4, 20.3) and the wave calculation with η1 = 0.160 and a = 13.61 μm. (e) Experiment at (1.408, D4, 19.5) and the wave calculation with η1 = 0.185 and a = 13.55 μm. (f ) Experiment at (1.536, D4, 19.1) and the wave calculation with η1 = 0.200 and a = 13.50 μm. The data in (e) is the same as the data in Fig. 3c.
