3S technology
DESCRIPTION
The 3S technology is based on the expansion of a pre-swirled gas flow in a Laval nozzle. At the same time, due to the transition of a part of the potential energy of the gas flow to kinetic during its acceleration to supersonic speeds, a sharp drop in the static pressure in the flow occurs, which is accompanied by its strong cooling.
