Mitigation of swirling flow with a vortex rope by passive installations—Theory, simulations, and experiments

This work is focused on reduction of swirling in cases from hydraulic machinery and, thus, mitigation of instabilities associated with swirling flow. We study this problem analytically using the torque integral equation, numerically using computational fluid dynamics (CFD) simulations, and experimen...
