2018年12月1日 · The BBDB technology using air as a working medium to convert wave energy can be classified into OWC technology, but the energy conversion process of it can also be understood as follows: wave energy is converted into mechanical energy of the buoy first, then the mechanical energy by subsequent conversion system (may called the pneumatic PTO ...

2019年8月1日 · The Backward Bent Duct Buoy (BBDB) oscillating water column (OWC) wave energy converter (WEC) has been invented following the so-far most successful OWC navigation buoys in wave energy utilisation, with aims to build large and efficient OWC wave energy converters for massive wave energy production.

The OE Buoy is a version of a device known as the Backward Bent Duct Buoy (BBDB) which was invented in 1986 by wave energy pioneer and Japanese naval commander Yoshio Masuda. The company Ocean Energy Ltd. was founded in 2002 by Michael Whelan and John McCarthy. [2]

2023年11月15日 · The back-bent duct buoy (BBDB) can be used as a floating oscillating water column (OWC) wave energy converter, showing its potential and reliability in most previous prototype sea trials. In this study, an experimental test on a generic BBDB OWC model was conducted in a wave flume using irregular wave scenarios.

2022年1月1日 · The OE Buoy is a version of a device known as the Backward Bent Duct Buoy (BBDB) which was invented in 1986 by wave energy pioneer and Japanese naval commander Yoshio Masuda et al. 1988. It was deployed in half-scale test mode in Spiddal near Galway in Ireland for over 2 years between 2007 and 2009.

1:4th-scale prototype of BBDB (the OE Buoy) equipped with a Wells turbine being tested in Galway Bay, Ireland, about 2008. The ocean waves are an important renewable energy resource that, if...

14 understanding of the hydrodynamic performance for the BBDB OWC wave energy converter. In the 15 study, the boundary element method based on potential flow theory has been applied to calculate the basic 16 hydrodynamic parameters for the floating BBDB OWC structure and the water body in the water column 17 in the BBDB OWC device.

Results show that the total energy conversion efficiency of every chamber of the triplet BBDB device has a narrow unimodal response width to wave period and decreases with the increase of wave height.

2017年6月16日 · BBDB，即 insidious Big Brother DataBase，Emacs 的主流信息管理／地址簿扩展包。 EIEIO 则很显然是 “Enhanced Implementation of Emacs Interpreted Objects” 的缩写， 也就是 Emacs Lisp 版本的 Common Lisp CLOS, Common Lisp Object System。 因此 EBDB 就是 “Enhanced implementation of emacs interpreted objects/common lisp object system version of the insidious big Brother DataBase“。 1 为什么重写？

2024年11月17日 · 本教程将结合程序代码及css控制站工程，讲述如何基于ph47代码框架的bbdb固件版本，为开发自己的ahrs姿态解算算法提供完善支撑环境，以及数据分析手段。
