摘要
建立了双波长激光全息干涉测试系统,测定了多组分气液传质液相侧边界层内的浓度场分布.结果表明,距界面0.01mm处的浓度仍远未达到热力学平衡值,说明界面附近存在相当大的传质阻力.还观察了气液传质时界面附近的湍动现象.
A self-designed micro holographic interferometer with two-wavelength lasers is used to measure the concentration profiles near the interface of liquid side in the multicomponent gas-liquid mass transfer process.It was discovered that the measured concentration at a distance of 0.01mm away from the interface was far from the thermodynamic equilibrium value.This shows that large resistance exists near the interface. Experiments show there is turbulence near the interface during interphase mass transfer.
