舰船尾流气泡数密度分布的实验模拟

为了能在实验室中为评估激光、超声探测舰船气泡尾流的检测技术提供检测对象，提出了基于电解产生氢气泡定量模拟实际舰船尾流气泡数密度的方法．依据电化学及气泡动力学原理推导了金属丝通电电流与气泡数密度的关系，在对舰船尾流场气泡数密度估计的基础上，给出了在船池中为布置在水中的金属丝通上给定的电流，模拟驱逐舰远场气泡尾流的具体方案，实验表明该方法对于舰船远场气泡尾流场的模拟比较右神

Simulating density distribution of bubble number in a ship′s far field wakes

To provide the evaluation of detecting technologies using lasers or ultrasonic with a measurement object in a laboratory for evaluating the detecting technology of ship bubble wakes by using laser or ultrasonic in a laboratory,a method to quantificational simulate the bubble number density in the ship′s wakes was proposed,which was based on electrolyzing water to produce hydric bubbles.The relationship between the electric current through a metal filament with the bubble number density was deduced according the electrochemistry and the bubble dynamics.The scheme simulating the bubble number density in a destroyer′s far wakes was put forward based on evaluating the bubble number density in a destroyer′s wakes by the electric current passing the metal filaments in a pool.The experiment shows that the method is efficiency in simulating the ship′s far field bubble wakes.
