MY RESEARCH
At the Industrial Multiphase Flow Laboratory (LEMI), I coordinate research projects on Multiphase Flow Applied to the Energy Industry. Among the lines of research, the following stand out:
- two-phase flow with dense gas
- experimental study of the transition of flow patterns in wells and pipelines;
- inverse emulsion in pipes, and
- gas separation in pumped oil wells.
A more fundamental fluid mechanics topic that has piqued my interest is a Hydrodynamic Stability of Two-Phase Flows of separate phases, such as oil-water flow in the core-annular annular pattern (figure) or stratified flow; more specifically:
- development of mathematical models of hydrodynamic stability, and
- numerical modeling of separate phase flows.
An interdisciplinary topic, which brings together mechanical, mechatronics and electronic engineering, which has been highlighted in our laboratory is the development of Instrumentation applied to the study of multiphase flows. It stands out:
- electrical impedance tomography with fast response wire-mesh type (figure);
- planar electrical impedance sensor for measuring liquid films.
