Abstract:

The following thesis work aims to investigate the behavior of a turbulent flow that develops inside an autoclave. The state of the art design of these industrial machineries is the reason for the production of a highly anisotropic turbulent flow that negatively affects the temperature distribution inside the chamber and threatens the success of the various heat treatment processes for which these machines are predisposed. A viscous and incompressible wall flow with a high Reynolds number has been studied, and then control techniques have been used to homogenize this flow. These consisted of a number of randomly activated velocity perturbations placed on the walls of the vacuum chamber. The impact of these sources was examined through LES simulations conducted on a grid of approximately 8 · 10^6 cells of size a few tens of millimeters. The whole was simulated using the open-source code PLUTO V4.4.2.
