虚拟设计工具在工业应用中变得越来越重要，这使得在原型构建和测试之前就可以了解前期设计的性能特征。在设计周期早期使用这些虚拟设计工具方法，不仅可以增加对产品性能的了解，还可以缩短交付期。本文对一台封闭式发电机组的冷却性能进行了详细的模拟计算。冷却风扇采用多个旋转基准风扇。同时，开发了一个简化的模型，取消了径向冷却风扇，并用风扇模型取代了发动机冷却风扇。以实测的风机性能数据作为模型的边界条件。这两个模型得到了相似的风量和通风面速度分布。基于用于冷却性能预测的简化风扇建模技术，实现了一个允许几何、网格划分和求解器运行自动化的设计工具。
Virtual design tools are becoming more and more relevant in industrial applications enabling upfront design performance charcateristics to be known prior to prototype build and testing. The use of these virtual design tool methodologies early in the design cycle can result not only in an increased understanding of the products performance but also in a lead-time reduction. In this work a detailed cooling performance simulation of an enclosed generator set was computed. Multiple rotating reference fames were used for the cooling fans. In parallel a simpified model was developed negating the radial cooling fan and replacing the engine cooling fan with a fan model. Measured fan performance data was used as a boundary conditon for the model. Both models yielded similar airflow rates and ventilation face velocity profiles. Based on the simplified fan modelling technique for cooling performance prediction, a design tool was implemented allowing the automation of geometry, meshing and solver runs.
