In the 21st century, sustainable energy supply is becoming increasingly important, and among renewable energy sources, hydropower is widely adopted around the world as a clean and efficient means of energy production. The hydraulic turbine, which is a central element of hydropower plants, plays a role in converting the power of water into electricity, and the guide vanes are essential for maximizing performance. Guide vanes play a crucial role in hydraulic turbines, and their design and analysis are indispensable for the development of hydropower technology. This article focuses on the guide vanes of hydraulic turbines and conducts a static analysis using the general-purpose structural analysis software AIFEM. *For more details, you can view the related links.

Wind turbines are mainly composed of parts such as blades, pitch control systems, gearboxes, generators, yaw control systems, and hubs. The hub connects the base of the blades to the main shaft of the wind turbine, and the blades experience complex alternating loads such as thrust, torque, and bending moments. Speed is transmitted from the hub to the main drive system through pitch bearings. Therefore, it is necessary to strictly manage the strength and lifespan requirements of the hub throughout the wind turbine. *For more details, you can view the related links.

In this case, we will introduce the modal analysis and static analysis of the turbine rotor using the structural analysis software AIFEM. The analysis results obtained with AIFEM demonstrated the effectiveness of the software through comparison with reference data (a certain commercial software). The model subject to analysis consists of a hub, shroud, and seven blades, forming the turbine rotor. The shape data used is in .stp format, and a mesh model was created using the mesh creation tool within AIFEM. *For detailed content of the article, you can view it through the related links.

In gas turbines and steam turbines, the design and optimization of blade cooling structures is a very important issue for designers. The first stage of the turbine can achieve high thermal efficiency as it withstands high temperatures, which opens up infinite possibilities for structural design and fine-tuning to prevent turbine damage under high temperatures and high centrifugal forces. One efficient method to solve this design problem is shape optimization, which involves automatically varying the design parameters of the cooling structure. *For more detailed information, please refer to the related link.

Ansys CFD tools such as Fluent and CFX receive strong support from engineers for evaluating fluid dynamic behavior in design, along with various options and tools used for mesh creation. These tools provide valuable information and insights regarding the performance to be evaluated. Moreover, they enable automated optimization and design exploration workflows that include CFD. In addition to improving design and shortening development time and design cycles, these tools significantly enhance the development process by increasing information about the impact of various design variables on performance (product behavior) during the initial design phase, where there is a high degree of freedom in decision-making. *For more details, you can view the related links.

In conventional thermal and nuclear power plants, steam and combustion gases are used as working fluids to drive turbines and generate electricity. In this case, we will introduce a design method for axial flow turbines using supercritical carbon dioxide (sCO2) as the working fluid, which reaches a supercritical state under relatively mild conditions using CAESES. The supercritical state exhibits properties that are intermediate between gas and liquid, and due to its high density and heat capacity, it has the potential to improve cycle efficiency compared to using gases below the critical point. *For more detailed information, please refer to the related links.

The blades used in aircraft engines and gas turbines become very hot, so cooling air is supplied to the countless holes on the blade surface through cooling passages provided inside the blades. In conventional design methods, automatic optimization was considered difficult due to the complexity of shapes, robustness of mesh generation, and computation time. However, this case presents an example of fully automated optimization using CAESES. *For more detailed information, please refer to the related links.

In March 2024, China drilled a 10,000-meter oil well in the center of the Taklamakan Desert, making it the first of its kind in the country and the second in the world. It is difficult to ascend into the sky, and even more challenging to descend to the ground. For aerospace, an altitude of 10,000 meters is significant, but when it comes to going underground, 10,000 meters can be said to represent the limits of human technology. For every 100 meters dug into the ground, the temperature increases by about 2°C, and pressure also rises. At a depth of 10,000 meters, one would be exposed to temperatures exceeding 200°C and pressures exceeding 130 MPa. *For more detailed information, please refer to the related links.
