Abstract

This study aims to enhance the comprehension of internal flow phenomena in axial turbomachines by employing the quasi-three-dimensional approach. By investigating the flow characteristics in both the meridian and vane-to-vane planes, a comprehensive understanding of the turbomachine's performance can be achieved. Specifically, the research focuses on a turbine stage, which comprises a stator and a rotor. The theoretical modeling phase involves solving complex dynamic equations that govern the intricate internal flow behavior. To validate the theoretical models and gain insights into real-world flow behavior, advanced numerical simulations are conducted using specialized computational fluid dynamics (CFD) software tailored for turbomachines. These simulations enable the examination of flow patterns, pressure distributions, and other vital performance parameters. The outcomes of this study hold great potential for enhancing the optimization and design of axial turbomachines, leading to improved overall performance and efficiency. By utilizing the quasi-three-dimensional method, this research provides a deeper understanding of the internal flow mechanisms within axial turbomachines. The analysis in the meridian plane offers valuable insights into the flow path from the inlet to the outlet, while the investigation in the vane-to-vane plane sheds light on the intricate interactions between adjacent blades. This comprehensive approach allows for a holistic evaluation of the turbomachine’s behavior. The findings from this study can contribute to the advancement of axial turbomachine design and optimization. The enhanced understanding of the internal flow phenomena can guide engineers and researchers in develo** improved turbomachines with higher performance and efficiency. Ultimately, this research may lead to significant advancements in various industrial applications where axial turbomachines are employed.
