搅拌罐作为一种搅拌混合设备广泛应用于石油、化工、生物、造纸等行业,搅拌的类型可以是固液、液液、气液等多相流动问题,在石化行业中,固液搅拌比较常见。本文综述了搅拌罐内固液两相流数值模拟的方法,从固体颗粒浓度、搅拌功率、搅拌时间三个方面概述了国内外搅拌罐固液两相流数值模拟的研究现状,为搅拌罐的结构优化和工况优化提供了理论支撑。 Mixing tank as a mixing equipment is widely used in petroleum, chemical, biological, paper and other industries, the type of mixing can be solid-liquid, liquid, gas and liquid multi-phase flow problems in the petrochemical industry, the more common solid-liquid mixing . In this paper, the method of numerical simulation of solid-liquid two-phase flow in stirred tank is reviewed. The current research status of solid-liquid two-phase flow in stirred tank at home and abroad are summarized from three aspects of solid particle concentration, stirring power and stirring time. Structural optimization and optimization of working conditions provide theoretical support.
