摘要
Abstract
In order to investigate a new cooling structure of trailing edge in small turbine engine blades,a numerical study was performed to simu-late the flow and heat transfer characteristics of micro scale cooling structures and draw conclu-sions of the influence of different Knudsen num-bers and different structures.The pressure loss, heat transfer coefficient and overall cooling effi-ciency under different conditions were calculated and compared.关键词
