Trinomial Expansion of Kinetic-Energy Coefficients for Ideal Fluid at Motion of Two Spheres Near Their Contact

摘要

The trinomial asymptotic expansions of potential flow kinetic energy in an ideal fluid are constructed for the motion of two spheres of variable radii in the vicinity of their contact. Based on these expansions, it is possible to study the process of two pulsating gas bubbles approaching up to their contact.
