Abstract
Vertical wiped film evaporators (VWFE) have found wide application in chemical, food and especially, fiber industries. In this paper, a mathematical simulation is represented for the vacuum evaporation dissolution process of Lyocell solution (reed cellulose, N-Methylmorpholine N-oxide (NMMO) solvent, water) in VWFE. The Turbulent Flow model in geometries with rotating parts and the frozen rotor approach in COMSOL Multi-physics 5.4 were used for simulation of the solution flow in VWFE. Comparing the obtained simulation results with experimental details, we show the effect of our simulation method.
