SOME OBSERVATIONS ON AIR FLOW PATTERNS AROUND AND IN A CONFINED HOLLOW CONE SPRAY

摘要

Some observations on air flow patterns around and in a confined hollow cone spray are described. In a circular duct the action of the spray is to cause the induced flow and, to a lesser extent, a forced flow to neck down near the spray and pass through an annular eddy region of back flow near the wall of the duct. If the liquid supply pressure is increased, separation of the main flow occurs earlier and the contraction increases.
