Numerical Investigation on Cooling Performance of Rectangular Channels Filled with X-Shaped Truss Array Structures

Abstract: In this study, different layout schemes for an X-shaped truss array channel are designed to explore the application of an X-shaped truss array structure in the mid-chord region of turbine blades. The flow and heat transfer performance of X-shaped truss array channels for three layout schemes are numerically investigated. The influence laws of the subchannel height ratio (h/H, 0.2 to 0.4) regarding the cooling performance of the channel with three subchannels are also analyzed. Then, the corresponding heat tran… Show more

“…Recently, due to the rapid development of the advanced manufacturing method, i.e., additive manufacturing (AM), many turbine blade designers have focused on enhancing cooling performance in the channels using different complex structures, such as lattice-frame materials [10,11]. Kaur and Singh [12] printed different strut-based lattice structures using resin and detailed the endwall heat transfer characteristics.…”
