This paper describes design of centrifugal-foam apparatuses (CFA) for direct gas cooling. The absence of lubricant in compressed gas allows considering this method of cooling rather perspective. Different liquid and gas dynamic processes have been researched on CFA with different angles of contact element openings. Hydraulic resistances of gas phase are defined, borders of stable functioning are detected: modes with "fall-off" of liquid though holes of perforation of contact element when gas flow is insufficient, "drowning" of conic contact element with liquid with lower feed and "hanging" of liquid with higher feed of it on contact element. Hydrodynamic CFA modes are categorized. Experiment results are interpreted as non-dimensional functional dependence.
