Abstract Evaporation rates of low-density water aerosols in a cylindrical acoustic resonator were investigated experimentally, motivated by the potential use of water droplet aerosols in two-phase thermoacoustic devices. Measurements of water aerosol evaporation rates were conducted using a novel direct visualization method combining mass balance quantification based on the light scattering from water droplets and two-dimensional PIV measurements with the droplets acting as the flow visualization particles. Water droplet aerosol evaporation was monitored at a location between the resonator pressure and velocity anti-nodes, while being subjected to a low frequency (110 Hz) acoustic standing wave with various acoustic pressure amplitude (APA) values. Application of the acoustic field was found to significantly increase water droplet evaporation rates, exhibiting a linear dependency on the applied APA in the range 600 Pa

应用低频声场提高水滴蒸发率

摘要 由于水滴气溶胶在两相热声装置中的潜在用途,对圆柱形声谐振器中低密度水气溶胶的蒸发率进行了实验研究。水气溶胶蒸发率的测量是使用一种新的直接可视化方法进行的,该方法结合了基于水滴光散射的质量平衡量化和二维 PIV 测量,水滴作为流动可视化粒子。在谐振器压力和速度波腹之间的位置监测水滴气溶胶蒸发,同时受到具有各种声压幅度 (APA) 值的低频 (110 Hz) 声驻波的影响。
