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
  • Applied Fluid Dynamics
