Computational fluid dynamics simulation of multiphase flow in packed sieve tray of distillation column

CFD gas–liquid simulation of oriented valve tray

“…Comparing the two approaches, the Euler-Euler approach was considered more suitable for simulating gas-liquid two-phase flow on the column trays [6,13,14].…”

“…(13) and (14), with different corresponding parameter values, were compiled into UDF by predecessors in our simulation.…”

“…With the experimental data of the oriented valve tray column by Zhang [32], Eqs. (13) and (14) were fitted, and the parameter values obtained as a 1 =1. …”

“…Therefore, the three parameters were relatively in good agreement and from distribution of relative errors, they decreased along with the increasing of liquid load, which was in agreement with refs. [13,29,34].…”

“…The parameters in Eqs. (13) and (14) were a 1 =1.475, a 2 =1.385, a 3 =0.216, a 4 =21.542, a 5 =1.0687.…”
