Investigation of the Shape of a Lying Drop in the Gravity Field and Phenomenon of a Drop Jump During the Transition to Weightlessness

The shape of a drop lying on a non-wettable solid substrate and the phenomenon of a drop jump from the substrate during the transition to weightlessness are investigated experimentally, theoretically and numerically. A mechanical model of the jump of the drop is proposed. The shape of a lying drop is calculated, and it is shown that the height of the drop depends on the volume of the drop nonmonotonically. The radius of the contact area of the...
