The commercial market for our product is very large and includes plant installations and industrial facilities that use extensive piping systems such as nuclear power generation, chemical process plants etc. The technology proposed here can play a critical and imminent role in addressing an important safety concern in pressurized water reactors where orifices are used in the emergency core cooling systems (ECCS) in conjunction with throttle valves. Another application of our product is in reciprocating compressors where resonant pulsation in the piping can be managed through the judicious use of a well-designed orifice-type element. In summary our product will provide the needed resistance in the hydraulic flow-path of plant installations/devices in a variety of industries without the flow transients and instabilities that are commonly associated with orifice plates leading to high-performance, high-reliability systems with significantly reduced risk. The novel orifice type flow control element resulting from this proposal would help alleviate instabilities in liquid rocket propulsion systems and test facilities for rocket engines that usually are initiated or amplified at the orifice plates. Our product will addresses a severe shortcoming in NASA's test facilities since orifices/venturis are commonly used and are quite often responsible for resonance and structural vibrations observed in the piping system. Design of the new control element proposed here can be tailored to provide the required resistance in the flow path without the risk of cavitation or whistling/resonance/vibration in the test loop. The new orifice design can also be used in segmented solid propellant rockets where they can prevent low frequency oscillations from amplifying, thereby keeping thrust levels stable.
