摘要：In this work we analyze the case of a upward two-phase vertical jet. We performe a calculation of the two-phase system, in which we use a ensemble averaged two-phase system. We reduced the equations to its 2D form and we use an integral technique. For that purpose we use form functions that contain the information of the functional dependence on the horizontal direction. The function form were obtained from a turbulent liquid jet calculation using kepsilon model. The obtained results show a reasonable behavior but due to the simplifications we used the solution does not follow the real system.
