Abstract
The induced noise types of automotive turbochargers in passenger vehicles have been already displayed in Chap. 2. Aerodynamic noise types, such as pulsation, rotational, growling, and whining noise, are generated from airflows in compressors of turbochargers by interactions between the fluid (charge air), solid surface (turbocharger), and fluid (ambient air) at their interfaces. Rotordynamic noise types like unbalance whistle, constant tone, high-order harmonic noise, and wear noise are created from rotordynamics of turbochargers by interactions between the fluid (oil), solid surface (turbocharger), and fluid (ambient air) at their interfaces.
