Work summary
Working with fluid mechanical questions mainly with numerical softwares, Computational Fluid Ddynamics (CFD). Main areas of applications are coupled to the hydro power industry with a particular interest in hydraulic engineering and fish migration questions. I am also working with processes coupled to flow in porous media.
Courses
Regarding education I am involved in the following courses:
- Computational Fluid Dynamics
- Hydromechanics
- Applied mechanics
