Abstract

Abstract:

Objectives The effectiveness of cooling technology directly influences the performance and lifespan of gas turbine blades operating in high-temperature, and high-pressure environments. The research status of swirl cooling technology was reviewed, aiming to summarize and evaluate its application in enhancing cooling efficiency and reducing thermal stress, and systematically analyze the basic principle and performance of swirl cooling technology. Methods The review focused on the design of swirl cooling channels, the combined use of swirl and film cooling, and the impact of rotational conditions on heat transfer performance. Results The swirl cooling technology significantly improves blade cooling efficiency and reduces thermal stress concentration. Specifically, reasonable design of swirl cooling channel can achieve uniform distribution of cooling fluid, enhance the cooling effect and prolong the service life of the blade. Conclusions The application of swirl cooling technology in gas turbine blade cooling has broad prospects. Future research should continue to explore the optimized design of swirl cooling technology and its performance under various operating conditions. Additionally, the combination with advanced manufacturing technologies, such as additive manufacturing, can further enhance the design complexity and cooling efficiency of swirl cooling channels, providing reliable support for the efficient and stable operation of gas turbines.
