Multiphase fluids

Aims

The GFM group is working on several lines of research related with the behaviour of fluids, and especial those involving more than one phase. The main lines of research are: (i) experimentation and development of instruments for characterising multiphase flows; (ii) study of the drying of droplets using ultrasonic levitation techniques, which allows individual droplets to be analysed with a very high degree of detail and precision; (iii) characterisation of fluid atomisation and the study of spray drying in the ceramic industry; and (iv) simulation of complex scenarios involving both single-phase and multiphase fluids by means of Fluid Mechanics Codes (CFD).
