Numerical analysis of flow resistance and heat transfer in double wall configurations featuring solid and hollow pin-fins

With the aim of overcoming the inherent penalties of high flow resistance and limited heat transfer associated with conventional solid pin-fin double wall designs (DW-SPF), this study introduces a novel hollow pin-fin configuration (DW-HPF). A comparative analysis of the two conf...

Multi-scale investigation of cooling characteristics and structural arrangement effects in octahedral transpiration cooling structures

The internal heat transfer mechanism of periodically arranged transpiration cooling structures remains unclear. In this study, the differences in simulation results between the pore-scale method and volume-averaged method are firstly compared. After determining the appropriate si...
