Abstract
In recent decades, engine performance has become a primary focus for engineers in the aviation industry, driven by the critical need to optimize fuel consumption and reduce pollutant emissions. This emphasis on performance has led to in-depth investigations into phenomena that can increase losses and decrease engine efficiency. One such phenomenon is Transonic Vortex Shedding in turbine blades. This study begins with a comprehensive review of existing literature on transonic vortex shedding, a topic extensively analyzed due to its significant impact on performance losses. The literature review highlights various theoretical and experimental approaches previously undertaken to understand this complex phenomenon. It also identifies gaps in current knowledge and areas where further research is needed.
Following the literature review, a series of Computational Fluid Dynamics (CFD) simulations were conducted to explore the key characteristics of transonic vortex shedding
