Abstract

The work is aimed at presenting a successful case of complex industrial application of thermal-fluid dynamics CFD analysis on a finned aluminium shell for car audio amplifiers designed by ASK Industries S.p.A.Heat transfer phenomena taking place in such a device include conduction along the shell body, convective and radiative heat transfer between the shell external surfaces and the ambient air. Complexities (MI PIACE POCO) of physical and geometrical nature prevent simplified analytical or semi-empirical models from being applied. Hence, only an accurate CFD model, realistically reproducing the exact shape of the device and all heat transfer mechanisms involved in the system, can supply information correct and useful for improvement and optimization of the shell design. 3D steady-state simulations using the industrial Navier-Stokes CFD code Fluent 6.2 (© Fluent Inc.) were performed on a Linux cluster at the DIMeC.The simulations were cross-checked with surface temperature patterns acquired via infrared thermography. The comparison shows an excellent agreement between experimental and CFD temperature data and demonstrates a very good reliability of the numerical approach.
