Experimental study of thermosyphon operation when cooling the condensation part by drop irrigation

open access: yesMATEC Web of Conferences, 2017
The influence of drop irrigation of the condensation part on the thermosyphon operational mode was studied experimentally. The temperature and pressure fall was found in the internal space of the upper chamber after applying the liquid on the upper wall ...

Diffusion Induced Chaos in a Closed Loop Thermosyphon [PDF]

open access: yesSIAM Journal on Applied Mathematics, 1998
The dynamics of a closed loop thermosyphon are considered. The model assumes a prescribed heat flux along the loop wall and the contribution of axial diffusion. The well-posedness of the model which consists of a coupled ODE and PDE is shown for both the case with diffusion and without diffusion. Boundedness of solutions, the existence of an attractor,
