	1	Thermal and Structural Insight into Lightweight Lattice Channels for Active Cooling Technology显示文摘The active cooling technology that can reduce the combustor temperature is commonly used to protect the scramjet.In order to further improve the performance of active cooling,the structural weight reduction,cooling efficiency and stress level of the cooling channel must be considered simultaneously.In this paper,new types of lattice channels for active cooling were designed and compared with the conventional cooling channel in terms of weight reduction,thermal and structural performance.The results showed that,at the same channel height,the cooling channel with staggered lattice arrays has the optimal comprehensive performance:the weight reduction effect reaches 39.93%;the wall temperature drops significantly,and the maximum Nu number is 2.155times of the conventional channel.The flow field analysis showed that horseshoe vortices formed by the impact effect and hairpin vortices near the trailing edge are the main factors of heat transfer enhancement.The disturbed boundary layer and the excited turbulent kinetic energy also contribute much to enhance the heat transfer.In addition,due to the HTE-induced increment of metal tensile strength,the system reliability of lattice channel is better than the conventional one.
