关于客户
本案例研究的客户是威斯康星大学麦迪逊分校的发动机研究中心 (ERC)。 ERC 是一家主要研究和教育机构，致力于研究内燃机 (IC) 发动机的基础知识和应用。该中心的学生研究人员平均约有 50 名学生，其中一半应用和开发计算机模型来模拟内燃机的流动和燃烧。随着政府排放标准变得更加严格，ERC 的工作变得越来越复杂，需要将更多的物理学纳入模拟，将更多的几何细节纳入网格。
挑战
威斯康星大学麦迪逊分校的发动机研究中心 (ERC) 是内燃机 (IC) 发动机研究和应用的领先机构，在复杂内燃机几何形状的网格生成方面面临着重大挑战。这些复杂性包括带阀门的进气口和排气口以及活塞/衬套缝隙等复杂的细节。 ERC 的工作涉及应用和开发计算机模型来模拟内燃机中的流动和燃烧，每个发动机模型都需要计算网格来解决定义其问题的湍流、化学和流动方程。随着政府排放标准变得更加严格，将更多物理原理纳入模拟并将更多几何细节纳入网格的需求也随之增加。第二个主要挑战是在这些几何复杂的网格建成后对其进行网格分辨率研究。
解决方案
ERC 采用了 ANSYS ICEM CFD Hexa，该工具可以从各种格式读取数据或从模型所需的所有几何细节中进行构建。该工具灵活的分块方法使得构建能够捕获这些几何细节的结构化网格成为可能。一旦建立了块，就可以轻松地在本地改变分辨率以进行网格分辨率研究。 ANSYS ICEM CFD Hexa 还能够将网格导出到 ERC 的求解器。该中心在过去三年中一直使用 ANSYS ICEM CFD Hexa，并且其在 ERC 中的使用量持续增长，为他们的网格生成和解析挑战提供了全面的解决方案。

Case Study
Integral Plant Maintenance
Mercedes-Benz and his partner GAZ chose Siemens to be its maintenance partner at a new engine plant in Yaroslavl, Russia. The new plant offers a capacity to manufacture diesel engines for the Russian market, for locally produced Sprinter Classic. In addition to engines for the local market, the Yaroslavl plant will also produce spare parts. Mercedes-Benz Russia and his partner needed a service partner in order to ensure the operation of these lines in a maintenance partnership arrangement. The challenges included coordinating the entire maintenance management operation, in particular inspections, corrective and predictive maintenance activities, and the optimizing spare parts management. Siemens developed a customized maintenance solution that includes all electronic and mechanical maintenance activities (Integral Plant Maintenance).

Hydro One Leads the Way In Smart Meter Development
In 2010, Ontario’s energy board mandated that time-of-use (TOU) pricing for consumers be available for all consumers on a regulated price plan. To meet this requirement, Hydro One needed to quickly deploy a smart meter and intelligent communications network solution to meet the provincial government’s requirement at a low cost. The network needed to cover Hydro One’s expansive service territory, which has a land mass twice the size of Texas, and its customers live in a mix of urban, rural, and remote areas, some places only accessible by air, rail, boat or snowmobile. Most importantly, the network needed to enable future enterprise-wide business efficiencies, modernization of distribution infrastructure and enhanced customer service. To meet these needs, Hydro One conceptualized an end-to-end solution leveraging open standards and Internet Protocols (IP) at all communication levels. The utility drew upon industry leaders like Trilliant to realize this vision.

Monitoring of Pressure Pumps in Automotive Industry
A large German/American producer of auto parts uses high-pressure pumps to deburr machined parts as a part of its production and quality check process. They decided to monitor these pumps to make sure they work properly and that they can see any indications leading to a potential failure before it affects their process.
