针对可扩管波能转换器的辐射波开放问题，建立了一个全面的线性数学模型。这个充满海水的装置位于海面以下，与沿着它的长度运行的波浪发生复杂的相互作用。其结果是，在满足一定条件的情况下，管中的凸起波的振幅增加，并通过功率输出机制捕获波浪能量。该装置的成功优化意味着从更大宽度的海浪（捕获宽度）中捕获能量。为此，研究了入射重力波、辐射波和凸起波之间的复杂相互作用。新的结果表明，捕获宽度与入射波的吸收、管上做功造成的能量损失、不完全调谐和辐射波有关。新的结果还表明，波-结构相互作用决定了瞬态凸起波的振幅、相位、衰减和波数。这些预测与实验观察结果相吻合。
A comprehensive linear mathematical model is constructed to address the open problem of the radiated wave for the distensible tube wave energy converter. This device, full of sea water and located just below the surface of the sea, undergoes a complex interaction with the waves running along its length. The result is a bulge wave in the tube which, providing certain criteria are met, grows in amplitude and captures the wave energy through the power take-off mechanism. Successful optimization of the device means capturing the energy from a much larger width of the sea waves (capture width). To achieve this, the complex interaction between the incident gravity waves, radiated waves and bulge waves is investigated. The new results establish the dependence of the capture width on absorption of the incident wave, energy loss owing to work done on the tube, imperfect tuning and the radiated wave. The new results reveal also that the wave–structure interactions govern the amplitude, phase, attenuation and wavenumber of the transient bulge wave. These predictions compare well with experimental observations.
