A magneto-rheological brake (MRB) is designed and embedded in a swirl generator apparatus in order to control the runner speed. Several swirling flow configurations are obtained slowing down the runner speed. The main challenge for MRB is associated with its operation under water conditions. As a result, two magneto-rheological fluids (a conventional one and one based on ferrofluid) are selected together with an appropriate sealing solution to avoid expelling the solid particles. Firstly, a commercial magneto-rheological fluid (MRF 336AG) manufactured by Lord Co. is tested in MRB. Secondly, a nano-micro composite magneto-rheological fluid, with 35% volume fraction of the micron-size iron particles (SMR 35%Fe), designed and manufactured by Magnetic Fluids Laboratory from Romanian Academy—Timisoara Branch was selected for experimental investigations. The mechanical solution designed for MRB is presented. The magneto-rheological properties determined for both MRFs are compared. Challenging investigations were performed at several runner speeds with MRB under water conditions. A relative speed variation behaviour associated with the runner rotation has been identified due to rupture and rebuild of large chain-like agglomerates in the MRF. This relative speed variation is directly correlated with the braking level of MRB. The conclusions are drawn in the last section together with the future work.
