Abstract: When hydraulic turbines like Francis ones are not operating at their peak efficiency, they can experience a phenomenon called the vortex rope, which originates from the slower swirling flow from the diffuser. This occurrence often leads to high-pressure pulsations in the conical diffuser, posing a significant challenge to the stable and safe functioning of hydraulic turbines. To address this issue, this paper presents a practical solution: the
