Abstract
Many industrial processes show, in some particular cases, two phase flows.
The two phase flow takes place when thermal and physical conditions like heat
exchange, pressure drop, viscous stresses, etc., have uncontrolled changes. In
other cases the process requires a two phase flow motion like in pipelines for
water-cool mixtures. In all these cases literature [1][2][3] shows the flow
observed inside the impeller is not properly described by classical Euler's
equations. It is still possible to approximately reformulate the Euler's equations
[2], when considering the interaction between gas and liquid phase. This
analytical approach, even tough incisive, has some important restrictions. It
must take into consideration the absence of thermal fluxes between the two
phases, the absence of vi
