研究了同一液体的两个表面建立接触的过程，例如两滴碰撞或雨滴落在水面上。数学公式基于具有表面张力的不可压缩、无粘性流体的假设。通过边界积分方法对具有简化几何形状的模型问题进行数值求解。结果表明，许多环形气泡形成并保留在接触表面之间。在文献中可以找到该过程的实验证据，该过程对于沸腾成核和雨滴凝结核的形成非常重要。
The process by which two surfaces of the same liquid establish contact, as when two drops collide or raindrops fall on water, is studied. The mathematical formulation is based on the assumption of an incompressible, inviscid fluid with surface tension. A model problem with a simplified geometry is solved numerically by means of a boundary-integral method. The results imply that a number of toroidal bubbles form and remain entrapped between the contacting surfaces. Experimental evidence for this process, which is important for boiling nucleation and the formation of condensation nuclei for rain drops, is found in the literature.
