Disclosed is a manufactured three-dimensional convex-concave fairing with attached vortex generators, for hydraulic structures such as bridge piers and abutments, whose shape prevents the local scour problem around such hydraulic structures. The device is a conventionally made concrete or fiber-reinforced composite, or combination of both, vortex generator equipped hydrodynamic fairing that is fit or cast over an existing or new hydraulic structure around the base of the structure and above the footing. The vortex generators are positioned so as to energize decelerating near wall flow with higher-momentum outer layer flow. The result is a more steady, compact separation and wake and substantially mitigated scour inducing vortical flow.

An autonomous filter device and a method for improving the filter life and performance is disclosed. The filter element is equipped with one or more sensors, adapted to measure one or more characteristics or parameters of the fluid, such as temperature, pressure, or flow rate. In response to the measured characteristic or parameter, the control logic within the filter element is able to determine an appropriate response. For example, the control logic may determine that a sudden, but temporary, blockage has occurred in the filter membrane. In response to this, the control logic may initiate a specific response designed to alleviate the blockage. This response may be a temperature change, a vibration, a change in fluid flow path, or some other action. The control logic will then determine the success of the response, based monitoring any change in the fluid characteristics. Based thereon, the control logic may alert the operator that the filter element must be replaced. Alternatively, if the response was successful in correcting the blockage, the control logic need not notify the operator, as the filter element is back to normal operating operation.

To reproduce sound in an extremely compact size, fluid injectors are used that can generate fluid flow sufficient to create a desired acoustic pressure wave, but which fluid flow operates in a manner that is decoupled from the desired acoustic pressure wave. Fluid flow within the fluid injectors needed to generate the desired acoustic pressure wave need not be directly proportional to the frequencies of the desired acoustic pressure wave. The fluid injector has a control input capable of altering fluid flow relative to a received control signal, which is generated by a controller in response to an electrical signal. The fluid injector produces fluid flow outward and inward in response to the control signal, thereby creating an acoustic wave proportional to the electrical signal. The devices herein may employ valves or not. Synthetic jets may also be used.
