利用有限元数值模拟软件Fluent,采用不可压缩流体流动的基本原理和流固热耦合有限元方法,对气垫炉中常用的圆形喷嘴进行模拟,得到喷嘴的不同出口速度、出口直径、温度等参数对漂浮力以及换热系数的影响。建立了几何模型和边界条件,模拟了换漂浮力以及传热特性,为气垫炉装置的研究与开发提供了依据。
The finite element numerical simulation software Fluent is used to simulate the circular nozzle commonly used in air-cushion furnace by adopting the basic principle of incompressible fluid flow and the fluid-solid coupled thermal-mechanical finite element method to obtain the parameters such as different outlet velocity, outlet diameter and temperature Impact on buoyancy and heat transfer coefficient. The geometric model and boundary conditions are established to simulate the change of buoyancy and heat transfer characteristics and provide the basis for the research and development of the air cushion furnace.
