Estudo experimental do fenômeno da ebulição em um termossifão de vidro
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2019-12-17)
Thermosiphons are devices used to exchange heat and are more efficient than conventional heat exchangers. For the correct dimensioning of the thermosiphons, specific correlations are required for the boiling process that ...
Two-phase flow frictional pressure drop prediction in helical coiled tubes
(Pergamon-Elsevier Science Ltd, 2020-12)
Based on the construction of different experimental databases, the frictional pressure drop in helical tubes for single-phase and water-steam two-phase flow was analyzed empirically. The aim of the present study is to ...
