Notes:
Interphase mass transfer between carbon dioxide gas and water has been investigated. The physical model used was the laminar concurrent flow of gas and liquid in a wide rectangular channel. Because of the high aspect ratio employed, the model was effectively one of parallel plates of infinite width.Three methods of solving the equations of change - the eigensolution method, the boundary layer theory, and penetration theory - were used to compute the diffusion coefficient of carbon dioxide in water from the experimental data. Calculated values of diffusion coefficients from the penetration theory checked well with those from the eigensolution method, but the values computed from the integrated boundary layer equation were about 10% higher.Results from the eigensolution agreed within 5% with the data of other investigators in the temperature range of 20° to 30°C.
