关于客户
Navatek Ltd. 成立于 1979 年,总部位于檀香山,是海洋流体动力学领域的领导者。该公司专门研究、开发和部署用于军事和商业用途的创新、先进的船体设计和相关技术。 Navatek 拥有多项与其水下升降体船体技术相关的美国专利,并以其在计算流体动力学 (CFD) 船体优化、减阻和集成推进系统方面的工作而闻名。该公司的技术原型已展示出诸多优势,包括更好的海况条件、增加的航程和有效载荷、降低的功率需求、更高的航速以及减少尾流冲刷。
挑战
Navatek Ltd. 是研究、开发和部署创新、先进船体设计及相关技术的领导者,在测试过程中面临着重大挑战。由于比例效应,传统的比例模型测试方法被证明是耗时、昂贵且不可靠的。这些过程所涉及的物理场的复杂性,包括瞬态、过渡湍流、具有自由表面的多相流,增加了获得可靠和准确结果的难度。这种情况需要一种更高效、可靠且更具成本效益的解决方案来测试其船体设计。
解决方案
Navatek Ltd. 向 ANSYS CFX 寻求解决方案来应对测试挑战。 ANSYS CFX 提供可靠的多相流模型,可以预测自由表面形状、力和空化效应。从 ANSYS CFX 获得的仿真结果已针对拖曳水箱实验进行了验证,并表现出极好的一致性。此外,CFX-Mesh 允许高度自动化、快速创建高质量网格,其膨胀层可确保出色的近壁分辨率。该解决方案不仅提高了测试过程的可靠性和准确性,而且还可以快速完成假设场景,为设计变化(例如附件放置)提供有价值的见解。

Drill ship power challenge: hybrid solution solves distribution issues
Aspin Kemp & Associates (AKA), a manufacturer of electrical power and control systems headquartered in Montague, PEI, encountered one with its hybrid power initiative, the first hybrid drill floor destined for installation on ultra-deepwater drill ships operated by Transocean, Swiss offshore drilling contractors. Since on-site modification was impossible and scrap recycling of any modifications was unacceptable, the enclosures had to arrive ready-to-install.

Ensures Tanker Safety and Emissions Compliance
Storage tanks are irregular in shape and a certain amount of mathematical modelling is required to get an accurate representation of volume and, more importantly, the weight of material in each tank. In addition, countries have different emission regulations, so the ships position needed to be accurately known in order to geotag emission data.

Real-time Networked Sonar System for Ships
A multinational, knowledge-based corporation that delivers marine electronics solutions is utilizing industrial Ethernet technology to help ensure that operations at sea are dependable and optimal. Based in Europe, the company has nearly 4000 employees working in 20 countries around the world, and produces high-tech systems for offshore oil and gas operations, merchant marine systems, and various applications for the defense and aerospace industries. The company produces products and systems used by merchant vessels and offshore installations for positioning, navigation, automation, as well as for surveying and monitoring the seabed, and for fishing vessels and fi sheries research. As one of the major suppliers of high quality marine electronics in the world, their products include chart plotters for yachts, triple redundant dynamic positioning systems for oil drilling rigs, and sonar and instrument systems for scientifi c research vessels. Products used for marine applications must be rugged enough to endure the corrosive effects of salt water, and be able to withstand excessive amounts of vibration and shock. For this reason, the company only uses DNV and GL certified products and components to ensure that their systems can meet the high standards required by the maritime industry.

Mitsubishi Electric's Edge Computing Solution Powered by Wind River VxWorks
Mitsubishi Electric Corporation, a global leader in factory automation (FA) applications, identified edge computing as a critical component of the Industrial Internet of Things (IIoT). The company aimed to enhance device and data security, reduce data traffic to the cloud, and enable faster response to network or device issues. In 2018, Mitsubishi Electric launched its first line of industrial hardware products designed for edge computing, the MELIPC Series. The primary development goals for MELIPC were to support the type of edge computing promoted by Mitsubishi Electric and to introduce advanced vision technology for device control. The flagship computer of the MELIPC line, the MI5000, was designed to combine real-time equipment control with high-speed data collection, processing, diagnosis, and feedback in a single machine. However, the development team needed a real-time control platform that could seamlessly integrate real-time control with proven analytic and diagnostic applications.
