Advance grooved heat pipe for space satellite thermal control system

Objective

The main scientific objective of this Project is to launch a new concept of axially grooved heat pipes fabrication with the advanced parameters (Qmax, low thermal resistance, high capillary potential, low senility to the gravitation field influence) to compare with the classical axially grooved heat pipes. The first general goal will be achieved by the mini-porous coating of the inner surface of the heat pipe envelope. The second goal will be achieved by the new kinds of working fluid, so called nano-fluids application as a working media inside axially grooved heat pipes to stimulate heat transfer.

Both concepts are based on the new nano scale phenomena of heat transfer enhancement in thin layer of the working fluid. The new generation of grooved heat pipes ensures an increase in heat transport capability, the maximum sustainable heat flux and heat transfer coefficients in three functioning modes corresponding to space application (parallel heating/cooling, anti-parallel heating/cooling and mixed heating/cooling for horizontal heat pipe position). The validation and optimization of the existing thermal and hydraulic models developed for the new generation of axially grooved heat pipes will be performed, as well as the experimental verification of the mathematical modeling.
