| Abstract: | Heat transfer performance tests and data analysis of plate-fin recuperators were performed for constant and varying flow ratios by the mass flow method, and Nu-Re criteria, vital for engineering application, were thereupon obtained. Numerical simulation was then used to analyze the temperature and flow fields in the recuperator passages with the conclusion that the heat transfer performance can be improved by changing surface roughness and structural shape of the recuperator's flow passage.
