Abstract
Disclosed is a method for causing bubbles in a fluid to coalesce into a coherent mass by use of a vessel having a cylindrical space therein wherein the fluid is caused to flow into the vessel at such a velocity that a vortex is generated to flow from one end of the space to the other while establishing a state in which the pressure on the center axis of the cylinder rises from one end toward the other, then reaches a maximal value and thereafter drops, and this coalescing of the bubbles is effected at the field near the axis of the vortex and between a position close to the inflow position and the position of the highest pressure. The method greatly facilitates deaeration.
