FIG. 4.

The nondimensional catapulting velocity Vpd* is proportional to the liquid mass fraction m* in accordance with Eq. (3). On polystyrene particles with rp = 135 ± 15 μm, drop coalescence is produced by inkjet printing as in Fig. 2(a) with rd/rp = 0.38–0.83 (m* = 0.06–0.48). The measurements scatter around Vpd*=0.26m* (the dashed line). In the inset, Vpd* is apparently not a linear function of m*.
