AI Technical Summary

⚠Technical Problem

Existing cooling systems for high-temperature components face a trade-off between cooling effectiveness and pressure loss, with increased fluid flow and pressure leading to higher operational costs and decreased efficiency.

⚗Method used

The implementation of cooling channels with an undulating profile that varies the period and frequency of undulations based on heat flux distribution, providing enhanced cooling in high heat flux zones while minimizing pressure drop in low heat flux zones.

🎯Benefits of technology

This approach achieves improved cooling efficiency with reduced pressure loss by optimizing cooling performance in high heat flux regions and minimizing pressure drop in low heat flux regions, thus reducing operational costs and enhancing component life and mechanical performance.

Abstract

A component includes a wall and a passage. The wall bounds an interior region and extends along an axis from a first end to a second end of the component. The passage extends within the wall between the first end and the second end. The passage includes an undulating profile comprising a plurality of undulations and extends along an extension axis. The undulating profile includes a first period measured along the extension axis between a first pair of adjacent undulations that is different from a second period measured along the extension axis between a second pair of adjacent undulations.
