Abstract

This article focuses on optimizing the radial airflow path of water vapor in a scraped-film evaporator to improve evaporation efficiency. Using a three-dimensional steady-state numerical simulation model, the study investigates vortex formation caused by shear forces near the scraper, which hinders vapor discharge and reduces efficiency. The introduction of a deflector plate is shown to weaken vortex intensity, guide airflow toward the axial flow region near the rotor wall, and increase axial flux without additional energy consumption. Through systematic evaluation of deflector position, angle, and length based on vortex intensity, flux ratio, and axial flux, the optimal deflector design reduced vortex area by 60.57% and increased axial flux by 15.62%, thereby enhancing vapor discharge and energy efficiency in the evaporator.
