現有波浪的紊动理論多借鑑于紊动水流的半經驗理論,把波浪运动簡化为恆定的水平水流,因而改变了波浪运动的特点,忽略了波浪垂直运动分速对紊动运动的影响,这是不够合理的。本文根据波浪流态的定性观察試驗,初步明确了波动水體內部流态沿深分区以及試驗室內的波浪临界雷諾数,並从波浪双向周期軌道运动的特点出发,推导了深水摆綫波紊动要素的計算公式,並用現場資料进行了驗証。最后还将深水波的紊动要素用鏡面映象的原理推广到浅水波紊动要素的計算。
The existing theory of wave turbulence mostly draws on the semi-empirical theory of turbulent flow and simplifies the wave motion to a constant horizontal flow, thus changing the characteristics of the wave motion and neglecting the influence of the wave velocity vertical velocity on the turbulent motion. Is not reasonable enough. According to the qualitative observation experiment of wave flow, the critical Reynolds number of wave in the interior of the fluctuating water body and the wave in the laboratory are clearly defined. Based on the characteristics of the two-way periodic orbital movement of the wave, Elements of the formula, and verified with the field data. Finally, the principle of mirror image is applied to the calculation of the turbulence elements in the shallow water wave.
