| Abstract: | The aim of this paper is to correlate the effect of pressure forces on a free drop with the surface coverage degree, namely, with the extent to which the drop surface is covered with surfactant. Our calculations show that for a covered degree less then 680 these forces are negative. This means that the forces exerted by the external liquid upon the drop are oriented towards the negative direction of the normal to the drop surface. In our opinion this force acts like a “hammer” generating the flow instability on the drop. |
