【摘要】:為了提高中心管振蕩水柱波浪能利用技術(shù)能量轉(zhuǎn)換效率,基于新的認(rèn)識和目前常用的2.4米導(dǎo)航燈標(biāo),對中心管尾部設(shè)計了三種模型并在造波水槽中進(jìn)行能量轉(zhuǎn)換性能試驗。試驗結(jié)果表明:直管型中心管俘獲寬度比最高達(dá)到了70.25%,但通頻帶寬度窄;加長喇叭口型中心管略好于喇叭口型中心管;在噴咀比為0.02條件下,加長喇叭口型中心管浮體有較高雙峰俘獲寬度比,波峰為40.0%,波谷為31.6%,通頻帶寬,為隨機波下高效轉(zhuǎn)換創(chuàng)造了條件。最高俘獲寬度比和雙峰通頻帶特性實驗數(shù)據(jù)結(jié)果都優(yōu)于歷史文獻(xiàn)值。根據(jù)試驗數(shù)據(jù)對一些適合小型海洋儀器供電的樣機進(jìn)行了設(shè)計,設(shè)計的樣機具有較高的性價比。
[Abstract]:In order to improve the efficiency of wave energy conversion of oscillating water column in the center tube, based on the new understanding and the 2.4-meter navigation lamp, three models are designed for the tail of the central tube and the energy conversion performance test is carried out in the wave-making tank. The experimental results show that the trapping width ratio of straight tube type center tube reaches 70.25, but the bandwidth of pass band is narrow, the lengthened bell mouth central tube is slightly better than the bell mouth type central tube, and the nozzle ratio is 0.02, The elongated bell-shaped central tube has a higher bimodal capture width ratio, with a peak of 40.0 and a trough of 31.6, which creates conditions for efficient conversion under random waves. The experimental results of maximum capture width ratio and bimodal passband characteristics are better than those of historical literature. According to the test data, some prototypes suitable for the power supply of small offshore instruments are designed, and the designed prototypes have high performance and price ratio.
