Numerical Simulation Research of Effects of Pulsating Air Flow on Liquid Film Evaporation Over Vertical Plates

  • 摘要: 建立了竖直平板降膜蒸发的二维物理与数学模型,采用数值模拟方法研究了脉动气流对降膜蒸发过程的影响,分析了在不同气流平均速度、振幅和频率下Sherwood数Sh的变化规律.结果表明:在脉动相对振幅为5/6时,竖直平板降膜蒸发传质效果提高了6.6%;Womersley数Wo大于26时,传质效果提高了8.3%.相对匀速气流,脉动气流可有效增强降膜蒸发的对流传质效果.
