We identify an incorrect term in the expression for the rate of change of circulation of a material volume including an interface between two fluids which appears in Br ns et al. (J. Fluid Mech., vol. 758, 2014, pp. 63 93). Brons et al. (2014) have analysed the vorticity generation from two-dimensional interfaces as well as the vorticity flux across such interfaces. In the expressions (2.18) for the vorticity source at the interface and (2.19) for the rate of change of circulation ddt of a material volume A which includes both fluids, a term (Formula Presented).
