喷雾干燥机是相当重要的在许多工业干燥操作，但他们的建模一直相对被忽视。在这里，我们总结了悉尼大学多年来的工作，研究了干燥机的基本流动行为，并使用商业CFD代码进行了建模。如果要研究流动稳定性和壁面沉积的重要问题，关键问题是需要进行三维瞬态计算，并包括受阻干燥和壁面相互作用模型。解决了需要以可承受的成本对流量进行适当解决的问题。
Spray dryers are of considerable importance in many industrial drying operations, yet their modelling has been relatively neglected. Here we present a summary of many years work performed at Sydney University investigating the fundamental flow behaviour in dryers and their modelling using a commercial CFD code. The key point to emerge is the need to perform three-dimensional, transient calculations and to include hindered drying and wall interaction models if important issues of flow stability and wall deposition are to be studied. This issue of the need to have proper resolution of the flow at an affordable cost is addressed.
