Latest Patents

Julian Sell holds a patent for the "Reduction of turbomachinery noise." This invention focuses on mitigating the acoustic components of noise that arise from the interaction of a turbomachine blade wake with downstream components. The technology involves the injection of fluid into the blade wake through a port in the rotor blade. By carefully selecting the mass flow rate of the injected fluid, the momentum deficit of the wake is reduced, which in turn increases the time-mean velocity of the wake and decreases turbulent velocity fluctuations. Additionally, the invention includes a suction technique that draws boundary layer fluid into the turbomachine blade, further enhancing noise reduction.
