文摘A computational fluid-dynamics model is presented for predictingthe two-phase two-dimensional liquid phase flow on a distillationcolumn tray based on the modification of Navier-Stokes Equation byconsidering both the resistance and the enhanced turbulence createdby the uprising vapor. Experimental measurement of the local liquidphase velocity on an air-water simulator of 1.2 m in diameter byusing the hot film anemometer is briefly described. Two of theconventional fluid-dynamic constants are readjusted for the case ofliquid flow on a tray by fitting the experimental data.
