This work enables to have an overview about main
instabilities such Kelvin-Helmholtz Instabilty, Rayleigh-Benard Instability
I hope you have understood each time the principle of the instability. I tried to illustrate each instability with a lot of examples and I hope you have enjoyed with them.
Instabilities presented in this work are not the only ones. Effectively inventoring all instabilities would be very difficult because of the number of them which is very important. Instabilities inventoried here are the main instabilities we can find in industry or Nature. There are also a lot of instabilities more unknown like Baroclinic Instability, Thermo-Haline Instability ..... But most of these instabilities look like one of the main instabilities listed in this work. It is for this reason that I didn't care about them and I speak only about the main instabilities which are articulated between two classes of instabilities : Internal Instabilities (main example : Rayleigh-Benard Instability) and Surface Instability (main example : Kelvin-Helmholtz Instability).
This work was very interesting for me because I enjoyed
to find a lot of examples, a lot of animations. I saw the manisfestations
of each instability what I find the most interesting in my work.
