Abstract
En 中文
Background: The blade unit of the tridimensional rotational flow sieve tray (TRST) makes the fluid form a rotational-perforated flow. The analysis of the flow properties of the unit is helpful to understand the hydrodynamic characteristics of TRST. Methods: The gas-liquid concurrent flow field was studied using the multi-fluid VOF method. The rotational and perforated flows at each section were analyzed based on the section rotational flow ratios. Significant findings: The section rotational flow ratio for the gas phase was between 0.6 and 0.85, and the transition section of the rotational and perforated flows of the liquid phase was z = 30 mm. The relationships between TRST and blade unit were clarified. The simulation performed for analyzing the mass transfer and structural optimization of the blade unit and TRST.
