Mass transfer to regular packings at low Reynolds numbers and under natural convection
Mass transfer coefficients for regular packings determined for low flow velocities show to be influenced by natural convection. In order to apply the coupling rule for forced and natural convection, mass transfer correlations for both pure regimes are required. Since no relationship for natural conv...
