Simulating heat and mass transfer in regular distillation column packing

Plane-parallel packing of Mellapack 250X type (without perforations) is considered. Equation systems are given that describe the motion and heat and mass transfer in a layer of liquid and vapor. Calculations have been performed on nonstationary heat and mass transfer in cells of several types by the use of the STAR-CD software and the subroutines Star-Design and Pro-amm. Graphs are given for the velocity and vapor pressure distributions in cells of circular and triangular shape, as well as for the oxygen distribution in circular cells.
