摘      要：Previous work showed that a one-dimensional,hyperbolic,transient five-equation two-fluid model can predict automatically the formation,growth,and subsequent development of slugs in horizontal and near-horizontal *** method was implemented in a finite volume numerical scheme e called 5ESCARGOTS *** with experimental data showed that it can be used to predict the flow pattern and statistical characteristics(slug velocity,length,and frequency).However,the capabilities of this approach have been tested only for water-air flows in a straight horizontal *** this work,we validate the application of the code to some unconventional ***,we test the possibility of slug capturing approach to describe and predict the relevant features of air/high viscosity oils or air/non-Newtonian fluids *** between some slug characteristics and empirical correlations,available in literature,are ***,we move from simple geometries toward more complex conditions that may be representative of actual application cases,also employing high viscous oils as liquid *** against experimental data shows results in reasonable agreement.
