Heat-Transport Characteristics of Capillary Looped Pipes.

Performance characteristics of pulsating heat pipes as integral thermal spreaders

In the recent past, Pulsating Heat Pipes (PHPs) have attracted the attention of many researchers as viable candidates for enhanced heat transfer through passive two-phase heat transfer mechanism. Although a complete theoretical understanding of operational characteristics of this device is not yet achieved, there are many emerging niche applications, ranging from electronics thermal management ...

Transport in Ultra-Thin Heat Pipes for Low Power Applications

Salt Loaded Heat Pipes: Steady-state Operation and Related Heat and Mass Transport

There is evidence suggesting that fluids in the root zone of many hydrothermal systems (at the brittle-ductile transition zone, about 3-4 km) can be highly saline. Therefore, fluid (state) can be expected to be in subcritical conditions and intensive multiphase convection may occur at those depths. The particular type of fluid-solid interaction and as well as the fluid state depends on the flui...

Transport in Flat Heat Pipes at High Heat Fluxes from Multiple Discrete Sources

A Review of Concentric Annular Heat Pipes

A detailed description of a concentric annular heat pipe (CAHP) operation is presented in low to moderate temperature ranges (50–200◦C). The steady-state response of a CAHP to various heat fluxes in the evaporator and condenser sections are discussed. Two-dimensional mathematical modeling of the fluid flow and heat transfer in the annular vapor space and the wicks are described. The fundamental...
