本案例研究中的客户是一家位于科罗拉多州朗蒙特的生物燃料公司。该公司的主要目标是成为将木质生物质转化为直接运输燃料的领导者。他们致力于利用先进技术来克服与高温生物重整相关的挑战。该公司专注于提高工艺的效率和有效性,特别是在气固分离、耐热应力和生物质转化率领域。他们还有兴趣探索与技术提供商的合作伙伴关系,以增强他们的能力并实现他们的目标。
挑战
一家位于科罗拉多州朗蒙特的生物燃料公司,旨在成为将木质生物质转化为即用运输燃料的领导者。然而,他们在高温生物重整过程中面临着一些挑战。关键挑战之一是小型气固分离分级机,其设计用于按尺寸从产品流中分离气体中的颗粒,以供后续分析。另一个挑战是确定材料的热应力抵抗力。该公司假设,将冷喷枪快速插入热室中会产生足以破坏样本的应力峰值。此外,生物质转化率取决于不断变化的粒度分布、颗粒形状和孔隙率。 CFD 中使用的物理属性取决于温度、压力和成分。
解决方案
该公司利用 Altair Technologies,特别是 AcuSolve 和 OptiStruct 来应对这些挑战。 AcuSolve 用于单向耦合有限质量粒子追踪、滑动变形网格、动态 LES 湍流模型、共轭传热和可变物理属性。 OptiStruct 用于热应力分析。该公司还使用带有元素插值的 acuProj 将瞬态温度场从 CFD 映射到样本的 FEA 网格。此外,他们还与 Star CCM+ DARS 动力学插件的创建者 LOGESoft 合作,将气固化学添加到他们的求解器中。 LOGESoft 用于估计流体的温度相关密度、粘度和热函。 Altair 的 AcuSolve Spalart-Allmaras 湍流、共轭传热、表面到表面辐射、含颗粒流体的用户 Rosseland 辐射模型以及热应力 OptiStruct 用于在实验室生物重整器中模拟热应力。

Vestas: Turning Climate into Capital with Big Data
Making wind a reliable source of energy depends greatly on the placement of the wind turbines used to produce electricity. Turbulence is a significant factor as it strains turbine components, making them more likely to fail. Vestas wanted to pinpoint the optimal location for wind turbines to maximize power generation and reduce energy costs.

Siemens Wind Power
Wind provides clean, renewable energy. The core concept is simple: wind turbines spin blades to generate power. However, today's systems are anything but simple. Modern wind turbines have blades that sweep a 120 meter circle, cost more than 1 million dollars and generate multiple megawatts of power. Each turbine may include up to 1,000 sensors and actuators – integrating strain gages, bearing monitors and power conditioning technology. The turbine can control blade speed and power generation by altering the blade pitch and power extraction. Controlling the turbine is a sophisticated job requiring many cooperating processors closing high-speed loops and implementing intelligent monitoring and optimization algorithms. But the real challenge is integrating these turbines so that they work together. A wind farm may include hundreds of turbines. They are often installed in difficult-to-access locations at sea. The farm must implement a fundamentally and truly distributed control system. Like all power systems, the goal of the farm is to match generation to load. A farm with hundreds of turbines must optimize that load by balancing the loading and generation across a wide geography. Wind, of course, is dynamic. Almost every picture of a wind farm shows a calm sea and a setting sun. But things get challenging when a storm goes through the wind farm. In a storm, the control system must decide how to take energy out of gusts to generate constant power. It must intelligently balance load across many turbines. And a critical consideration is the loading and potential damage to a half-billion-dollar installed asset. This is no environment for a slow or undependable control system. Reliability and performance are crucial.

Remote Monitoring and Control for a Windmill Generator
As concerns over global warming continue to grow, green technologies are becoming increasingly popular. Wind turbine companies provide an excellent alternative to burning fossil fuels by harnessing kinetic energy from the wind and converting it into electricity. A typical wind farm may include over 80 wind turbines so efficient and reliable networks to manage and control these installations are imperative. Each wind turbine includes a generator and a variety of serial components such as a water cooler, high voltage transformer, ultrasonic wind sensors, yaw gear, blade bearing, pitch cylinder, and hub controller. All of these components are controlled by a PLC and communicate with the ground host. Due to the total integration of these devices into an Ethernet network, one of our customers in the wind turbine industry needed a serial-to-Ethernet solution that can operate reliably for years without interruption.
