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...

Study about heat transfer coefficient of water-nanofluid in pulsating heat pipes

Pulsating heat pipe is an efficient heat exchange device which is being used for cooling and heating recovery. In the present work, we made a closed-loop pulsating heat pipe with six U-turns and we used water in our system. Moreover the use of water-Fe3O4 nanofluid was studied with two different filling ratios 40% and 50% and 1% mass concentration. At the end we calculated heat resistance and h...
