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 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.

An energy converting system as defined in claim 15, wherein the expander is positioned inside the inner concentric cone and the inner concentric cone includes hydraulic paths for inlet and outlet of the expander, so that the inner cone forms a self-contained compressor-expander-imploder unit.19. An energy converting system as defined in claim 15, wherein at least one of the plurality of vanes extends out to a portion of the intake.20. An energy converting system as defined in claim 14, wherein the compressor wheel is symmetric with respect to the drive shaft such that the compressor wheel is configured to flip 180°.21. An energy converting system as defined in claim 14, comprising at least one by-pass valve positioned on a portion of the compressor and configured such that the by-pass valve opens when the pressure inside the compressor is less than the pressure outside the compressor.22. An energy converting system as defined in claim 14, wherein the expander comprises a single-stage expander wheel having the plurality of blades, the expander further comprising at least two nozzles for injecting the first fluid toward the plurality of blades, the at least two nozzles positioned such that the forces exerted by the injected first fluid from the at least two nozzles counter balance the forces exerted by the compressor wheel.23. An energy converting system as defined in claim 14, wherein the expander comprises a plurality of expander wheels each having the plurality of blades, the expander further comprising a plurality of nozzles for injecting the first fluid toward the plurality of blades, the nozzles spaced and positioned such that summation of all reaction forces exerted by the injected first fluid from the nozzles counter balance the forces exerted by the compressor wheel.24.
