연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

The present disclosure is directed to an acoustically actuated flow valve having temperature-sensitive reed valves thereon. The flow valve and reed valves are configured to impart acoustical energy into a fluid flowing through the flow valve and one or more fluids downstream of the valve, leading to increased mixing of the fluids. The reed valves are further configured to be temperature-sensitive, thereby allowing more fluid to flow through the flow valve as the result of a change in temperature.

1. A flow valve assembly for modifying acoustical energy of a fluid, the flow valve assembly comprising: a body including— a base portion configured to receive the fluid into the body;one or more of tubes disposed therein configured to transport the fluid from the base portion through the body; anda bore extending therethrough;a valve actuator disposed in the bore of the body wherein the valve actuator is configured to be movable between a first position and a second position;a flow valve coupled to the valve actuator, wherein the valve is movable to an open position thereby allowing the fluid to flow therefrom, wherein the valve actuator and the valve are configured concentrically;a plurality of reed valves adjacent to an outer edge of the flow valve and configured to respond to fluid movement through the flow valve. 2. The flow valve assembly of claim 1 wherein the plurality of reed valves comprises a first metal having a first coefficient of thermal expansion and a second metal having a coefficient thermal of expansion different from the first metal. 3. The flow valve assembly of claim 1 further comprising a sensor configured to register one or more conditions in a fluid space proximate to the flow valve and the reed valves. 4. The flow valve assembly of claim 1 wherein the valve actuator is configured to be acoustically displaced thereby resulting in an oscillation of the flow valve from the open position to a closed position. 5. The flow valve assembly of claim 1 wherein the reed valves vibrate in response to the fluid movement. 6. The flow valve assembly of claim 1 wherein the reed valves are disposed on the flow valve. 7. The flow valve assembly of claim 1 wherein the reed valve is positioned in the fluid flow pathway. 8. The flow valve assembly of claim 1 further including a diaphragm positioned between the flow valve and the reed valves. 9. A method of operating a flow valve assembly to control a flow of a fluid, comprising: introducing a first fluid into a body portion of the flow valve assembly, the body portion including a flow valve, the flow valve being movable between an open position and a closed position;configuring the flow valve to oscillate from the closed position to the open position to introduce at least a portion of the first fluid into a fluid space adjacent to the flow valve;configuring a plurality of reed valves positioned concentrically with the flow valve to vibrate in response to energy imparted by flow of fuel and/or oscillations of the flow valve;imparting acoustical energy to at least one of the first fluid, the flow valve, the plurality of reed valves, or a second fluid in the fluid space adjacent to the flow valve. 10. The method of claim 9 wherein imparting acoustical energy comprises transferring energy to alter a vibrational frequency of at least one of the first fluid, the flow valve, the plurality of reed valves or the second fluid in the fluid space adjacent to the flow valve. 11. The method of claim 9, further comprising sensing one or more conditions in the fluid space adjacent to the flow valve, and wherein imparting acoustical energy comprises adaptively altering, in response to the sensing, the movement of the first fluid, the flow valve, the plurality of reed valves or the second fluid in the fluid space adjacent to the flow valve. 12. The method of claim 9 wherein imparting acoustical energy comprises propagating pressure waves of acoustical energy through the first fluid and altering a frequency of vibration in the first fluid. 13. The method of claim 9 wherein imparting acoustical energy comprises controlling the frequency, shape, pattern, and/or phase of a plurality of fluids in the fluid space adjacent to the flow valve. 14. The method of claim 9 wherein imparting acoustical energy comprises subjecting the first fluid to a pressure drop as the first fluid passes through the flow valve into the fluid space adjacent to the flow valve. 15. The method of claim 9 wherein imparting acoustical energy comprises inducing a frequency above about 20,000 Hz in at least one of the first fluid, the flow valve, the plurality of reed valves or the second fluid in the fluid space adjacent to the flow valve. 16. The method of claim 9, further comprising sensing a temperature or pressure in the fluid space adjacent to the flow valve and modifying the frequency, shape, pattern, and/or phase of the first fluid in response to the sensed temperature or pressure. 17.
