Numerical analysis

A parametric study was performed with the software Fluent ANSYS in laminar flow.

The four following parameters varied : 

- Fluid's viscosity : $\mu $ = {0.001, 0.25, 0.75, 1} Pa.s

- Tank's lenght : L = {1.5, 2, 2.5, 3, 3.5} m

- Inital water level : h = {0.2, 0.5, 0.7, 1.1} m

- Plan's acceleration : a = {1, g, 2.5g} m/s2

The elevation of water level obtained with Fluent match the theoritical expression for all the cases.

Therefore, theoretical expressions and Fluent's results of dissipation time and natural frequency will be compared in the next parts.
