Rotating heat pipe research towards novel heat transfer media

A rotating heat pipe set up will be built in the laboratory of P&E as part of a collaboration project with TATA Steel. In this test rig, the heat transfer performance of the heat pipe with a certain working fluid will be tested and quantified for various operational conditions. The test rig will enable testing working fluids up to 350 oC. Rotation frequencies up to 1000 RPM are enabled with a DC motor. The set up will be equipped with heat flux sensors. Research questions:

- What is the vapor channel resistance for various heat input/output  settings, operational temperature, rotational speed and working fluid amounts?

- What is the evaporation resistance as function of the abovementioned process parameters?

- What is the combined condensation and film layer thickness resistances for such process parameters?

- How is the comparison with modelled heat transfer characteristics?
