挑战
GE航空集团的系统业务部门负责设计和生产对喷气发动机和机身之间的接口至关重要的系统，其任务是为新飞机提供备用发电机（BUG）。该发电机用于在其他系统发生多次故障时提供电力。 BUG 必须安装在新设计的发动机上以接收机械动力，但保持独立于发动机以确保功能。它有自己的油网络、泵和油底壳，为发电机中的电磁部件和轴承提供润滑和冷却。润滑系统依靠重力排放将油从轴承腔返回到油泵所在的机载油底壳。该团队需要确保排水管的尺寸足够大，以允许最坏情况下的油流通过，这样油就不会积聚并导致轴承内产生过多的热量或任何其他不良影响。由于规模和计划时间的限制，需要一种分析方法来确定当前排水通道网络的能力和所需的最小规模。
关于客户
GE航空集团的系统业务部门负责设计和生产对于喷气发动机与安装发动机的机身之间的接口至关重要的系统。尽管 Systems 与 GE Aviation 密切合作，但其生产的产品差异化很大，许多用于发动机的典型设计工具并不非常适合 Systems 生产的配件。然而，通过利用 GE Aviation 及其数字工具团队的经验，Systems 能够使用 Flow Simulator 等工具来设计和分析对于生产下一代发电机和电气系统至关重要的子组件。
解决方案
该团队需要一个具有足够灵活性的工具来快速准确地对新系统进行建模并进行重新设计迭代。他们在 Flow Simulator 中找到了解决方案。该工具的图形用户界面 (GUI) 可以快速识别和设置由管道、弯头、连接处和静压室组成的复杂网络。基本的“构建块”样式设置允许每个元素适当链接，并自动考虑一个模型中多个不同分支的尺寸、形状、压力和流量的差异。 Flow Simulator 的结果通过 GE Aviation 所使用的经过验证的基于 Excel 的工具进行了验证。该系统包含允许使用多种配置评估几何形状的功能。该团队能够利用入口和出口腔的压力差以及重力馈送的高度方法来测试排水管的能力。一旦建立了初始模型，就可以针对各种压力、温度和几何形状快速测试设计迭代。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
