| Popis: | This paper deals with certain aspects of convective condensation phenomena and condenser behaviour in capillary-driven cooling loops (CPL or LHP) studied in the LAPLACE laboratory, Toulouse. The effects of phase distribution, in the condenser, on the stability and the reliability of the whole system were studied. A model is proposed for convective condensation at low mass fluxes in a microgravity-like situation. The numerical results are in good agreement with experimental data. On increasing the mass flux, both numerical and experimental results suggest that the stationary state no longer exists, and intrinsic instabilities occur and develop in the condenser. The effects of such instabilities, as well as flow regime transitions, on loop behaviour remain an open question. |
