Pentagram marks correspond to half the mass flux for fluidelastic instability threshold and circle filled marks correspond to transition zone.…”

“…It is worth mentioning that the mass velocity, G, for the estimation of u g and u l is based on the minimum cross sectional area. According to Sim & Mureithi (2014), better damping estimations for two-phase air-water systems (low pressure systems) are calculated by using the two-phase friction multiplier, φ 2 L0 (L0 stands for the two-phase mixture flowing as liquid), defined in Marchaterre (1961) apud (SIM; MUREITHI, 2014) as follows:…”

“…For instance, Sim & Mureithi (2014) suggest that φ 2 l0 in Eq. 3.40 can be calculated according to Marchaterre (1961) given by Eq. 3.42.…”

“…6.8, it can be said that two-phase pressure drop estimations based on the homogeneous model for φ 2 l0 are not satisfactory for j l 0.02, 0.183 and 0.553 m/s. However, it was decided to test its implementation with the Sim's model because of Figure 6.8: Comparison between experimental results obtained in Kanizawa & Ribatski (2017b) and the two-phase pressure drop ∆P 2φ estimated according to Kanizawa & Ribatski (2017b), Marchaterre (1961) its simplicity. In this manner, the Sim's damping model was implemented with the homogeneous void fraction model, the homogeneous two-phase multiplier given by Eq.…”

This project has been funded by the Brazilian National Council for Scientific and Technological Development-CNPq (grant numbers 481044/2010-8 and 307369/2013-7) and the doctorate scholarship from CAPES Foundation, for which I am grateful. I would like to thank the São Carlos School of Engineering, University of São Paulo, USP-Brazil, which welcomed me and has been my home during these six years of study and work. My big and sincere thank goes to my promoter, Prof. Leopoldo de Oliveira, who supported me in several ways since the very first time we got in touch via e-mail. Thank you, Leopoldo, for always be in a good mood and available for answering my questions, for your respect to my time and your consideration. Thank you for sharing your knowledge about experimental structural dynamics and, specially, for making feasible the ideas I proposed for our tests. I use to make a joke: if I would necessitate enriched uranium, Leopoldo would provide. Thanks for the freedom you gave me to make the decisions in the present project. My sincere thanks go to Prof. Gherhardt Ribatski, who let me be part of the project. Also, I would like to thank your "encouraging phrases", they were used to challenge me in the subject that you imparted to me, as well as, to take me out from my comfort zone in many times. Moreover, I would like to thank you for considering myself to write the chapter for the Encyclopedia of Two-Phase Heat Transfer and Flow, it was an invaluable experience. I would like to express my thanks to Prof. Fabio Kanizawa, who designed and mounted the test bench in which I performed the experimental campaign. Thank you for your patience and to be willing to help. Actually, this paragraph should be longer, however, I already gave a speech when you left São Carlos.
