CFD simulations
- Kelvin-Helmholtz instability (inviscid flow)
Simulation setup:
* Wavelength of the disturbance l = 1.264 m.
* Velocities: fluid_up = 0.25 m/s, fluid_down =0.1 m/s.
* Same densities.
* Multiphase setup.
* Inviscid model with periodic conditions.
- Natural convection phenomena in a bidimensional box
Simulation setup:
* Boussinesq approach.
* 10 cm x 10 cm box filled with air.
* Adiabatic top and bottom walls, T_hot_wall = 305 K and T_cold_wall = 290 K.
* Steady state setup.
* Laminar model.
- High-speed train design optimization
- Cyclone separator
Simulation setup:
* Realizable k-epsilon model selected for rotational flow.
* Mass balance conservation.
* Fluid: air with inlet speed v = 2.33 m/s.
* Pressure outlets.
- Electronics cooling
- Flow over a cylinder
Simulation setup:
* The dimensions of the domain are 0.4 m x 0.2 m while the diameter is d = 0.01 m.
* The fluid is water with an upstream velocity of v = 0.025 m/s.
* Re = 250 thus laminar flow.
* Unsteady state simulation setup.

* AoA = 4º.
* Pressure farfield.
* Steady state simulation.
- Axial fan flow
Simulation setup:
* Two angular sections of an axial fan, a rotor and a stator.
* Rotational periodicity considered between blades of the same section.
* w = 310.6 rad/s.
* Mixing plane interface between rotor and stator to remove unsteadyness.
* Steady state simulation.
Piston - Cylinder
Simulation setup:
* Dynamic mesh
* Heat source term
* Inviscid flow
