METHOD OF REDUCING FRICTION OF TURBULENT GAS FLOW

摘要

FIELD: machine building. ^ SUBSTANCE: proposed method comprises directing flow along surface containing damping cavities for killing high-frequency pulsations. Said flow interacts via perforated holes with said damping cavities wherein flow turbulent pulsations are killed. Flow is laminated to reduce friction resistance. Note here that said cavities have different volume and communicate with flow via different number of perforated alternating holes. ^ EFFECT: higher efficiency of decrease in friction resistance due to damping lower-frequency pulsations. ^ 1 dwg
