Leveraging design space exploration to improve aircraft ECS system performance
Modern commercial aircraft environmental control systems (ECS) contain a complex and interrelated set of subsystems that must work together to ensure the performance of the aircraft. These systems are expensive to run, necessitating the need to improve energy efficiency while providing the best possible customer experience. An example of this is the use of bleed air from the engine core flow to pressurize and heat the main cabin, as well as supply hot air to the aircraft's anti-icing system. Prior to distribution, this air is mixed with cold air from the engine bypass to achieve the...

The ability to predict something before it happens is something most of us wish we had in our arsenal. Weather forecasters think they have this ability, but we all know better. While it may be nice to know the answers to some questions ahead of time, it is essential for car manufacturers to be aware of any possible design roadblocks as early as possible in the development process. Virtual thermal analysis is a process used during vehicle development to determine whether components in close contact with hot surfaces - such as the engine or exhaust - exceed recommended temperatures. Possessing this knowledge is vital as it allows engineers the opportunity to preserve functionality and prevent accelerated aging in these components. Running a full virtual thermal analysis is ideal because it provides the most accurate results, but it is a method that because of time and cost can ideally only be run once, and at the end of development for validation only. Of course, by that point in the process it is too late in the game (or too expensive) to make major changes. After a recent review of their virtual thermal analysis process, the thermodynamics computational fluid dynamics (CFD) team at global automobile manufacturer Volvo found that Siemens PLM Software’s STAR-CCM+® software allowed them to run full vehicle thermal models at earlier stages than possible with competitors’ software.

共轭传热与CFD技术帮助您更快的计算部件温度
电机等工业产品中涉及三维非对称热流动问题(如燃气轮机、汽轮机、涡轮增压器、换热器、锅炉、窑炉等),有限元分析(FEA)是从热应力和疲劳角度来评估这些机械耐久性是否满足需要或者容易出现问题。但为什么不使用计算流体力学(CFD)中的CHT功能为您的FEA工程师提供最精确的部件温度,作为其热应力计算的输入呢?当机械的流体温度随着时间变化很显著时,这是特别适用的。 当进行金属部件的热分析时,你就会发现每种传统方法都有它自己的挑战和局限: 方法一:使用有限元方法(FEA),不包括任何流体分析,因此没有考虑到流体和固体之间随时间变化的热传递的动态特性。 方法二:使用有限元方法(FEA),结合低保真度的一维流动计算工具。不考虑复杂的三维湍流流动对流体固体之间温度场的相互影响。内置在一维流动的工具中的假设不再有效或者可用。 方法三:使用有限元方法(FEA),结合三维CFD和传热系数(HTCs)。其计算很大程度上取决于每次迭代CFD和FEA求解之间的多次来回的数据传递。此方法这种方法是近似的(因此具有较低的精度),以及计算缓慢,费力,和容易出错的,不利于自动化的多仿真设计探索。 为了使在很短的时间内算得非常精确的温度场成为可能,需要使用内置在CFD工具中动态耦合方法或者共轭传热(CHT)方法,同时计算流体和固体域的温度场。 如你即将在网络研讨会中见到的,在主流的仿真软件中都具有CHT方法,...
