摘要:
在对喷雾干燥塔内流动特点认识的基础上，采用较为成熟的计算流体力学（CFD）模型及算法，建立适用于硝基胍物料喷雾干燥的应用模型。利用Gambit软件对几何模型进行网格划分，导入Fluent中进行数值计算，预测塔内流场分布情况、液滴含水率及颗粒平均粒径等。通过测试样机干燥产品的含水率、产品粒度分布及场内温度分布等发现，预测结果与实验结果大致吻合，说明模拟结果有一定的准确度和可靠性。
Abstract:
Computational fluid dynamics (CFD) model and algorithm were used to establish suitable application model for spray drying of nitroguanidine based on the understanding of the flow characteristics of materials in spray drying tower. The geometric model was meshed by Software Gambit. It was introduced into Fluent for numerical calculation to predict flow field distribution, droplet moisture content and the average particle size in the tower. In the experiment, the moisture content, particle size distribution and temperature distribution in the field of dried products tested by the experimental prototype are used to verify the correctness of the mathematical model. The predicted results are similar to the experimental results, indicating the simulation results have certain accuracy and reliability.
