Анализ эффективности баллона с криогенной заправкой и баллона высокого давления для дроссельной системы охлаждения

Abstract

This study presents a comparative analysis of different fill configurations for plate-fin heat exchangers (PFHEs) used in heat recovery systems of small-scale gas turbine units (MGTUs). The authors evaluate four types of channel geometries: semi-circular straight, semi-circular zigzag, circular straight, and wavy. Using Pareto analysis, the research identifies trade-offs between hydraulic losses, mass, and length. Results show that wavy channels offer the best compactness but higher pressure drops, while semi-circular zigzag channels minimize hydraulic losses. The findings highlight the importance of optimizing heat exchanger design to balance efficiency, size, and performance in MGTU applications.
