Analysis on Dynamic Characteristics of Rotating Flow Tubes With Multi-Channel and Different Flow Directions
摘要
Abstract
Turbine blades were the key components for gas turbine power output.To work normally in high temperature environment,cooling tube channels need be set inside the blades.The blade has complex dynamic behaviors under the joint action of internal fluid and its own rotation.The blade was simplified into a rotating pipe conveying fluid tube with multi-channel and different flow directions.The kinetic equation was derived with the energy method and the complex modal analysis was carried out.The effects of the flow direction,the velocity and the rotating speed on the stability and modal transition phenomena of the system were revealed with numerical examples.关键词
