## Computational Fluid Dynamics module

### Introduction

Description of the underlying theory and schematic list of the problems this application can solve.

In this application the Navier Stokes equations are solved bla bla..

### Structure

#### Fluid types

• Incompressible fluid
• Compressible fluid

Constitutive laws

• Newtonian
• No-Newtonian
• Bingham plastics
• Variable yield model

#### Kinematical approaches

• Eulerian
• With free surface (level set)
• Without free surface
• Lagrangian PFEM (implicitly with free surface)

#### Solution strategy

• Fractional step
• Monolithic

Different solvers are availables (LINK TO SOLVER SECTION!!!!)

In both cases a Newton Raphson residual based strategy is used for linearizing the problem.

#### Elements

Linear triangular elements in 2D and linear tetrahedra elements in 3D.

Stabilization techniques availables:

• ASGS
• OSS

#### Boundary conditions

• Velocity boundary condition: Inlet of water
• Pressure boundary condition: Pressure can be imposed strongly or weakly...
• Wall boundary condition:
• Slip/no slip boundary condition
• Wall law
• Flag variable?????

#### Initial conditions

Initial condition both in velocity and pressure can be set.

#### Turbulence models

The user can chose wether to use or not a turbulence model. Those available in kratos are:

• Smagorinsky-Lily
• Spalart-Allmaras

#### HPC

The code can be run in shared or distributed memory:

• OpenMP:
• MPI:
