For this comparison, we are in the case without surface tension.
The measure of the amplitude isn't easy because Fluent is not realy provided for
quantitative study.

Moreover, we want verify that the theoretical amplification coefficient is the
same as the experimental one.
The problem is that the amplification coefficient depends on the wave number.
So, in order to measure precisly the experimental amplification for a particular
wave number, we would have to make a FFT of the result.

To conclude the quantitative study is too hard to fulfil in this project.
We can say that the amplification exists effectively for the predicted wave number, but
we can't say if the theoretical result corresponds to the experiments or not.
