Pranav Sriganesh, PhD candidate and student of Professor Ahmet Selamet, won the Student Paper Competition Award for his paper titledSilencer for high-frequency turbocharger compressor noise via an acoustic straightener” from The Institute of Noise Control Engineering (INCE).

Sriganesh says that the paper discusses the design and development of a unique silencer using various computational tools including acoustics and flow simulations to target high-frequency tonal noise (around 10 kHz) at the inlet of an automotive turbocharger compressor. “The task is rather challenging since typical silencers are tuned based on assumptions that are valid only at low frequencies (around 100 Hz),” says Sriganesh. This novel silencer will allow the implementation of high-performance, but noisy turbochargers in small passenger car engines to improve the overall efficiency while meeting vehicle noise standards. Other silencer applications that involve high-frequency air-borne duct noise also benefit from the concepts discussed in this paper.

“I am honored to receive this recognition from the experts in the field at INCE,” says Sriganesh. “My co-authors Dr. Rick Dehner and Prof. Ahmet Selamet have been instrumental in the success of this publication by not only advising me on the technical aspects of the paper but also helping me improve my ability to deliver an effective presentation. The award makes me excited for the experimental component that we plan to follow up on this computational work!”
