Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A summary of the objectives and conclusions reached in this project are: •A litterature search on post dryout heat transfer for pure refrigerants and for refrigerant-oil mixtures was performed and a comprehensive review written (Chapters 9, 10, and 11); •T ...
Lack of precision and inconsistencies in existing correlations, an attempt was successfully made to develop a new and more mechanistically based correlation (Kattan, 1996 [1]) for boiling inside plain tubes. This new general correlation is original in that ...
The conversion to the new alternative refrigerants caused by the greenhouse and ozone effects is now replacing nuclear reactor analysis and safety as the major driving force in two-phase heat transfer research. Extensive studies are underway on pool boilin ...
Two-phase flow pattern data have been obtained experimentally for R-407C flowing inside 12 mm bore sight glasses, which were located at the outlets of 3 m long, plain bore copper tube heat transfer test sections. The tests covered nominal mass velocities o ...
Intube flow boiling experiments for two new zeotropic refrigerant mixtures and R-502 have been carried out at three saturation temperatures over a wide range of local vapor qualities. The zeotropic mixtures tested were HP80 and HP62. Local flow boiling coe ...
Measurements ith tracer gases were performed, together with more classical temperature and air velocity measurements, on various ventilation systems installed in the test chamber of Sulzer Infra, in Winterthur. The test chamber was arranged to simulate an ...
