To develop and validate a high-fidelity integrated aeroacoustic model of a data center server and evaluate the acoustic and thermal performance of commercial sound insulation materials.
Simulated server acoustics using transient computational fluid dynamics (CFD) coupled with computational aeroacoustics (CAA).
Validated the numerical model against experimental airflow curves and acoustic measurements in a data center server environment.
Tested two commercial acoustic insulation materials for sound attenuation and conducted steady-state thermal assessments compared to an uninsulated baseline.
Simulations achieved less than 10% deviation from experimental measurements for both fan curve data and sound pressure levels (SPL).
Application of commercial acoustic insulation materials reduced noise emissions while causing only a 2°C increase in steady-state server temperature.
