摘要
以烟用恒温干燥箱为研究对象,介绍干燥箱的基本原理和结构。通过CFD数值模拟和试验的方法对干燥箱的流场进行研究。采用SOLIDWORKS三维建模软件建立干燥箱的结构图,利用FLUENT软件仿真得到恒温干燥箱达到稳定状态时的温度场、压力场和流速场。恒温干燥箱内9个测量点的温度和风速测量值与数值模拟结果吻合较好,验证了数值模拟模型的正确性。而恒温干燥箱内部温度场的均匀性是干燥箱主要的性能指标之一,研究发现叶轮转速对干燥箱温度均匀度有较大的影响,合适的转速有利于改善干燥箱内温度场的均匀性,为干燥箱的优化设计提供参考依据。
The thermostatic drying oven for cigarettes was the research object.The basic principle and structure of the thermostatic drying oven for tobacco were introduced.The flow field of the drying oven was studied by CFD numerical simulation and experiment.The structure diagram of the drying oven was established by SOLIDWORKS.The temperature field,pressure field and velocity field in the steady state were obtained by using FLUENT software.The measurement results of temperature and wind speed at nine points in the thermostatic drying oven are in good agreement with the numerical simulation results,which verifies the correctness of the numerical simulation model.The uniformity of the temperature field in a thermostatic drying oven is one of the main performance indexes of the drying oven.The results show that the impeller speed has a great influence on the temperature uniformity of the drying oven.Appropriate speed is helpful to improve the uniformity of the temperature field in the drying oven,which provides a reference for the optimal design of the drying oven.
