A three-dimensional two-phase flow model with phase change inside a tube of petrochemical pre-heaters

► Modeling and simulation of crude oil flowing inside an horizontal tube of petrochemical pre-heaters. ► An eulerian-eulerian two-phase flow model is used in this formulation. ► A group of seven pseudo-components is used to predict the thermal cracking of the petroleum. ► Vaporization is considered in this model.
