Fig. 5: Capillary wave velocity.
From: Compound jetting from bubble bursting at an air-oil-water interface
Dependence of dimensionless velocity vd/vc of the selected dominant capillary wave on the dimensionless oil layer thickness h/R during bubble bursting at the oil-covered aqueous surface, where \({v}_{{{{{{\mathrm{c}}}}}}}={\left(\frac{{\gamma }_{{{{{{\mathrm{e}}}}}}}}{{\rho }_{{{{{{\mathrm{w}}}}}}}R}\right)}^{1/2}\) is the inertial capillary velocity. Inset shows that vd is measured when the selected dominant wave goes through the position with an angle of θ = π/4 corresponding to the vertical cavity axis. Error bars are calculated as the standard deviations of data of at least 10 runs.
