The pulsating heat pipe (PHP) can be used to transfer massive reduce the thermal damage cutting tool when machining difficult-to-cut materials. To select a better open PHP, performance was experimentally investigated in this study. operating characteristics of different types working fluids under flux were analyzed compared with closed PHP. Visual experiments established verify experimental cha...

Abstract Pulsating Heat Pipes (PHP) are promising and effective passive two-phase heat transfer devices in terms of high capability, efficient thermal control, adaptability low cost therefore they have been extensively studied the last years. Many authors estimated fluxes at evaporator condenser area only average values based on first principle considerations. In present study application an in...
