挑战
飞机发动机燃烧室的设计是一个复杂的多学科过程,涉及航空 CFD、燃烧、传热 CFD、动力学、热学、机械和寿命预测。 GE 全球研究中心与 GE 飞机发动机公司合作,负责开发先进的燃烧室设计技术,以满足严格的新产品引入 (NPI) 分析要求。此过程中的一个重大挑战是以自动方式生成高质量网格。网格质量在自动化设计过程中起着至关重要的作用,影响分析的准确性。此外,网格划分过程需要可编写脚本,无需人工干预。完整的燃烧室扇形模型需要全六边形网格,以确保分析准确性。
关于客户
本案例研究的客户是通用电气 (GE),这是一家跨国集团,业务涉及航空、电力、可再生能源、数字工业和医疗保健等多个领域。在这个特殊案例中,重点是通用电气的航空部门,特别是通用电气飞机发动机公司。 GE飞机发动机公司是为商用、军用、公务和通用航空飞机提供喷气式和涡轮螺旋桨发动机、零部件、集成数字、航空电子设备、电力和机械系统的领先供应商。该公司正在寻求开发先进的燃烧器设计技术,以满足积极的新产品引入 (NPI) 分析要求。
解决方案
为了应对这一挑战,完整的燃烧室扇区模型分为三个主要部分:内衬、外衬和圆顶组件。每个组件进一步分为一组子组件。工程解决方案涉及使用 prt2tetin 脚本生成 tetin 文件、生成六角形重放文件以及将网格集成到组件或完整燃烧室模型中。此过程生成了完整燃烧室扇区模型的全六角形网格。该解决方案中使用的技术是 ANSYS® CFD。该解决方案还具有 Unigraphics 的简化界面,可轻松实现精确的几何转换、用于高质量网格的新颖且独特的块策略,以及用于自动网格生成的出色脚本功能。

Underground Mining Safety
The goal was to produce a safety system to monitor and support underground mining operations; existing systems were either too simple (i.e. phone line) or overly complex and expensive, inhibiting deployment, and providing little-to-no support in event of an accident. Given the dangerous nature of the mining work environment and the strict regulations placed on the industry, the solution would have to comply with Mine Safety and Health Administration (MSHA) regulations. Yet the product needed to allow for simple deployment to truly be a groundbreaking solution - increasing miner safety and changing daily operations for the better.

Real-time Monitoring and Unified Management Platform for PV Plant
As PV power plants continue to increase, centralized management and information integration become thorny problems.Enterprise PV systems mainly supply power for their own needs and may sell excess power to the power company whereas Photovoltaic (PV) power plants specialize in solar energy collection and then feeding the energy into the grid.To transmit the data of the PV systems wired or wireless networks can be used. However, wireless networks have the advantage of flexibility and are the best choice for those who want quick deployment.Taking into account the requirements of wider coverage and long-distance transmission, the existing fiber-optic networks had many shortcomings ie high cost, complicated wiring and long construction period, and it may also have been necessary to excavate walls, drill holes, embed wires, or even destroy the original building structure. After evaluation, the Juli Group decided to adopt an easy installation and easy expansion wireless network system for early completion of this project.

Rapid and Simple Installation Provides Access to Critical Data
The customer needed to monitor non-contact alignment and non-contact process temperature in different positions along a 100-meter production line. Space around the line is tight and operators and forklift trucks are passing by constantly. Installation of correctly routed cables from sensors back to the control station would have been expensive and would have taken too long and caused too much disruption to ongoing operations.

Real-Time IoT Tracking and Visualization Improve Manufacturing
Shimane Fujitsu, a wholly-owned subsidiary of Fujitsu and a leading manufacturer of business notebooks and tablets, set out to improve processes where factory inspections found product errors. Prioritizing product rework based on shipping date was challenging, and it caused Shimane Fujitsu to incur additional shipping fees. The company needed a way to collect data to better track the location of products in the rework cycle as well as monitor progress in real time. The collected data would also help process analysis for future improvements.

Automatic Vision Inspection Solution for Product Traceability
With greater market demand for food safety, traceability is receiving increasingly more attention in the food and beverage industry as well as the packaging industry. One of the world's leading providers of beverage containers required a system to identify bar codes and alphanumeric characters on ink-jet-printed labels at a run rate of 7 units and minimum 99.9% accuracy. Since there were few engineers in the factory, the customer sought to implement a reliable system with an easy-to-use GUI for workers with a less technical background.
