Disclosed is a bionic fish single-degree-of-freedom modular structure based on a cam mechanism. The bionic fish single-degree-of-freedom modular structure comprises a plurality of modules which are sequentially connected, wherein the foremost one of the modules is a fish head module, and the last one of the modules is a fish tail module; each module in the modules comprises a rack, a rotating shaft is arranged in the center of the rack in a penetrating mode, the second end of the rotating shaft of the previous module is connected to the first end of the rotating shaft of the next module through a universal coupling, the next module is connected with the previous module through a swing connecting piece, and the effect that the modules swing in a plane is achieved, wherein the swing connecting pieces comprises cylindrical cams, pin shafts, first bearings and second bearings; and through combination of the modules, the swimming postures of fishes can be achieved. A single-degree-of-freedom modular bionic robot fish is designed according to the swimming postures of sailfish and can be driven by a single motor, and the fluctuation postures of the bodies of the fishes are achieved through motion transmission of a mechanical structure; and modular design is adopted, and different swimming postures can be achieved by replacing the modules.

A discharge system includes a mixing vessel and a feedstock input in fluid communication with the mixing vessel. A solvent input is in fluid communication with the mixing vessel. A discharge output is in fluid communication with an outlet of the mixing vessel to discharge effluent. A method for generating turbulence on a liquid surface within a discharge system includes supplying a mixing vessel with feedstock fluid and solvent fluid to generate a liquid mixture and a gas pocket in the mixing vessel. The method includes supplying an impinging solvent fluid through a nozzle extending from a first end of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture.
