Zusammenfassung:A method of determining an aperture area of a nozzle hole in a droplet jet device including a flow channel through which a liquid flows and the nozzle hole configured to spray the liquid, the method including determining the aperture area [m2] of the nozzle hole so that a jet flow of the liquid sprayed from the nozzle hole is fragmented into droplets, the liquid having a value of ρ0.45/σ determined from a density [kg/m3] of the liquid and a surface tension [N/m] of the liquid in a range no lower than 300 and no higher than 900, and a kinematic viscosity coefficient [m2/s] of the liquid in a range no lower than 1.0E-6 and no higher than 2.0E-5.
