Connection with the Real Problem
OpenFOAM
CFD (Open Field Operation and Manipulation, Computational Fluid Dynamics)
is an open source software extensively used to get fluid
problem solutions through their specialized libraries. The complete C++ modules
run in a Linux operating system basis.
ParaView
(Parallel Visualization Application) is a computer tool which can run under
Windows OS. This tool has been designed to visualize data sets either small or
very large.
As
a powerful and strongly recognized tools, it is convenient at this time to learn
them for their use in a short time future application (master’s thesis).
-
To
learn OpenFOAM CFD tools and tutorials
on Linux OS with special attention in mesh generation.
-
To
learn Paraview on Windows.
-
To
create simple (small scale) example problems in OpenFOAM.
-
To
visualize the result of these examples in Paraview.
-
To
discuss issues related to the transition to the Real (Professor Dancey / Dillon) Problem.
Connection to the Real (Professor
Dancey / Dillon) Problem
When
water is moving in an open-channel (like a river), sediments are forced to move
with the flow. There is a general theory which explain this phenomena in a
simply way. According with this theory, particles are forced into the flow if
the velocity of the flow reaches a critical value. Such a linear theory is not
enough to explain what is really occurring in the vicinity of the particles,
and how and why some particles are really moving under this critical velocity.
Professor Clinton Dancey and Brandon Dillon have been working in the Real Problem ”Incipien sediment motion
in a turbulent, open-channel flow”.
Last year, the project began to be developed by Brandon as a class project and
now as his Master’s Thesis research. This research focuses in the turbulent
flow in a 15m x 0.6m x 0.15m channel with a more detailed mesh at particle vicinity.
The goal is to reproduce the experimental data by simulated data using OpenFoam and Paraview software.
The
connection of the present course project with this Real Problem will be done at
the end of this course in order to establish the goals for a new Master’s
Thesis project.
