Comparison of heat-transfer performance of a flat-plate pulsating heat pipe based on heating orientation and cross-sectional shape of the pipe

Mechanical Engineering Journal, 2023
The effects of cross-sectional shapes of flat-plate pulsating heat pipes (PHPs) on heat-transfer performance were experimentally investigated. The flat-plate PHP, made of aluminum alloy, has a closed-end serpentine channel with 22 turns. Four PHP samples
