Stress analysis of Francis turbine runner based on fluid-structure coupling
摘要
Abstract
This study uses fluid-structure coupling （FSC） method to turbine runner under rated power and different working heads and the high working head. Calculations show that peak static stress occurs at shroud, and that this peak value decreases as the head increases operation. calculate the static stress of a Francis dynamic stress under rated power and the joint of blade trailing edge to the And the runner is safe and in stable关键词
