摘要
为了解决使用明纳特频率在计算舰船气泡尾流中微小气泡的谐振频率时存在的误差,得到舰船气泡尾流中微小气泡更准确的谐振频率计算公式。本文在中等大气泡的谐振频率计算公式明纳特频率的基础上,根据Rayleigh-Plesset方程,推导了适用范围更广的谐振频率计算公式,并给出了迭代解,以及适当范围内的二次迭代解。该计算公式可以对舰船气泡尾流中存活时间最久的微小气泡的谐振频率进行计算,对声尾流制导鱼雷的频率选用具有一定的指导价值。
In order to eliminating the Minnat frequency formula's calculation errors of the resonant frequency for micro bubbles of ship wakes,and to get a more accurate calculation formula according to the Rayleigh-Plesset equation,the calculation formula of the resonant frequency with wider application range is derived based on the medium-sized bubble-Minnat frequency. The iterative solution is given,along with the second iterative solution within the appropriate range. The resonance frequency of the microbubble with the longest survival time in the bubble wake of the ship can be calculated by using the derived formula,which has a certain guiding value for frequency selection of the wake homing torpedo.
