Salt loaded heat pipes: steady-state operation and related heat and mass transport

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...

Steady State Operation of Cylindrical Loop Heat Pipe Evaporators

Loop heat pipe evaporators operating under steady state conditions were numerically investigated to describe evaporator characteristics and evaluate evaporator performance. Numerical solutions were obtained for conjugate flow and heat transfer in primary evaporator components. Two geometrical configurations used for cylindrical LHP evaporators, a non-bayonet evaporator and a bayonet evaporator,...

Heat and Mass Transport in Heat Pipe Wick Structures

A novel experimental approach is developed for characterizing the performance of heat pipe wick structures. This approach simulates the actual operation of wick structures in a heat pipe. Open, partially submerged, sintered copper wicks of varying pore size are studied under the partially saturated conditions found in normal heat pipe operation. A vertical wick orientation, where the capillary ...

Heat and Mass Transport in Carbon Nantubes

We have investigated heat and mass transport in singlewalled carbon nanotubes (SWNTs) using molecular dynamics methods. Particular attention was paid on the non-equilibrium dynamics at the interface between SWNT and other materials, which strongly manifests in nanoscale. In the first part, we have investigated the heat transport through the interface between SWNTs and surrounding argon matrices...
