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.

초록

An energy conversion system having two or more enclosures supported in a vertically-stacked configuration by an enclosure support. The enclosures are airfoil-shaped and enclose multiple oppositely-rotating fluid turbines. Fluid directing structures formed in the enclosure direct fluid into and out of the enclosure, including through the turbines. The fluid directing structures are parallel slats formed into the enclosure.

The enclosing structure of claim 1 wherein the symmetrical airfoil shape of the outer profile is formed by a left exterior surface of the leading and trailing enclosure surfaces that mirrors a right exterior surface of the leading and trailing enclosure surfaces about a chord line formed between the leading end and trailing end of the enclosure body. 3. The enclosing structure of claim 1 wherein the plurality of first spaces located in the leading enclosure surface is formed between a first plurality of parallel slats, the plurality of second spaces located in the trailing enclosure surface is formed between a second plurality of parallel slats. 4. The enclosing structure of claim 3 wherein at least one of the first plurality of parallel slats or the second plurality of slats is moveable between an open position for permitting fluid to flow through the plurality of first spaces or the plurality of second spaces and a closed position for preventing fluid from flowing through the plurality of first spaces or the plurality of second spaces. 5. The enclosing structure of claim 3 further comprising a movable panel for covering the first plurality of parallel slats and configured for selective movement between an open position where the plurality of first spaces are not blocked by the movable panel and a closed position for blocking the spaces. 6. The enclosing structure of claim 1 wherein the leading enclosure surface is convex in shape such that it bows outwards away from the enclosed area, whereby the convex shape guides foreign bodies located in front of the enclosing body around the leading enclosure surface to continue flowing past the enclosing body. 7. The enclosing structure of claim 1 further comprising an internal flow directing structure disposed in the enclosed area for redirecting fluid flowing through the leading enclosure surface and into the enclosed area. 8. The enclosing structure of claim 7 wherein the internal flow directing structure comprises a cowling having a flow-splitting nose for dividing a fluid flowing along the fluid flow path into at least two diverging streams of fluid, where one stream of fluid is directed towards each of the at least two turbines. 9. The enclosing structure of claim 8 wherein the cowling comprises a convex or concave flow-directing surface for each flow path joined together by the flow-spitting nose. 10. The enclosing structure of claim 1 further comprising a solid transition surface formed between the leading enclosure surface and the trailing enclosure surface wherein the turbine mount is positioned within the solid transition surface. 11. The enclosing structure of claim 1 wherein the trailing enclosure surface is parabolic in shape. 12. The enclosing structure of claim 1 further comprising an internal separator formed in the enclosed area between the leading end and the trailing end and having at least one opening for receiving the turbines, the internal separator forming a first enclosed section between the internal separator and the leading end and a second enclosed section between the internal separator and the trailing end, wherein fluid passing from the first enclosed section to the second enclosed section must pass through one of the openings in the internal separator and wherein the turbine mount is mounted to the internal separator. 13. The enclosing structure of claim 12 further comprising an internal flow directing structure disposed in the first enclosed area for redirecting fluid flowing through the leading enclosure surface through the at least one opening and into the second enclosed area. 14.
