Effect of Fluid Properties on Flow Patterns in Two-Phase Gas Liquid Flow in Horizontal and Downward Pipes
Tzotzi, C.; Bontozoglou, V.; Andritsos, N.; Vlachogiannis, M. (2011)This paper investigates the effect of gas density and surface tension on flow pattern transitions in horizontal and near-horizontal pipes. Experiments were conducted at atmospheric conditions in a 12.75-m long pipe with a ... -
Interfacial shear stress in wavy stratified gas-liquid flow in horizontal pipes
Tzotzi, C.; Andritsos, N. (2013)The scope of this study was to improve the Andritsos-Hanratty model for estimating interfacial friction factor and pressure drop in horizontal stratified gas-liquid two-phase flow. New experimental results (focusing on the ... -
A study of CaCO3 scale formation and inhibition in RO and NF membrane processes
Tzotzi, C.; Pahiadaki, T.; Yiantsios, S. G.; Karabelas, A. J.; Andritsos, N. (2007)The formation of CaCO3 deposits on RO and NF membranes was investigated in connection with permeate flux decline. Experiments, in the presence and absence of scale inhibitors, were carried out in a cross-flow membrane test ...
