中文摘要	在通常的气幕减阻技术中,由于气泡的不断流失容易产生能耗增大、减阻效果下降等问题。该文提出一种利用驻留微气泡的减阻技术。微气泡产生于阵列布置于航行体表面的微凹坑中,并在航行过程中稳定驻留于凹坑处,从而有效降低局部摩阻系数;微气泡通过电解水产生,并可反过来对电解反应进行自适应控制,从而自适应地控制供气量和气泡形状。通过初步数值模拟和实验,对影响气泡驻留的因素进行了定性的分析。设计了一种电解反应自适应控制的凹坑结构,用于气泡形状和电解反应的自动控制。通过数值计算,对一特定条件下驻留微气泡的理论减阻能力进行了讨论。; In air injection drag reduction, bubbles will be inevitably lost with water flow, and this may cause energy waste and goes against drag reduction. This paper provides a new method of drag reduction by trapped micro-bubbles. Micro-bubbles are generated in arrayed pits on ships by electrolysis reaction, and each bubble stably stays there, so as to reduce the local friction. Further, this electrolysis reaction in every pit can be adaptively controlled, so each bubble can automatically keep its volume and even its shape. To show the feasibility of this method, influencing factors on bubbles' stability are qualitatively discussed by numerical analysis and experiments. A special structure with a V-groove is given for adaptive control of electrolysis reaction. And the drag reduction ability of trapped micro-bubbles under a certain condition is predicted through numerical calculation.
