This research investigates the design and optimization of an exhaust silencer to reduce the noise generated by diesel generators under different load conditions. Initially, acoustic data obtained from generators under various load conditions were collected, forming the basis for the silencer design. The designed silencer was analyzed three-dimensionally using the finite element method in terms of acoustic performance, backpressure, and thermal behavior. The effectiveness of the silencer in noise reduction, its compliance with the regulatory limit values, and its impact on generator performance were thoroughly evaluated. Physical tests conducted after optimization studies and analyses demonstrated a high level of consistency between the analytical and experimental data.

Exhaust Silencer Acoustic Design and Optimization for Diesel Generators Under Different Load Conditions

Öz

This study presents the design and optimization of an exhaust silencer for diesel generator sets operating under various load conditions, with a focus on mitigating noise emissions. Acoustic data were collected across different load scenarios to inform the silencer design process. The proposed silencer was analyzed using finite element methods to evaluate its acoustic performance, backpressure characteristics, and thermal behavior. The analysis assessed the silencer's efficacy in noise attenuation, compliance with regulatory standards, and its impact on generator performance. The findings contribute to advancing noise control strategies for diesel generators, fostering the development of sustainable and regulation-compliant energy solutions.
