Effect of a Perforated Resonator on the Flow Performances of the Turbocharged Intake System for a Diesel Engine 2018-01-0678

The flow issues of the turbocharged intake system for a diesel engine are mainly introduced in this work and the effects of a multi-chamber perforated resonator which can efficiently attenuate broadband noise and has compact structure on the flow performances of the intake system is analyzed by contrast. Based on the acoustic grid resulting from pre-processing of 3D models for finite element analysis, a computational fluid dynamics flow simulation comparative analysis between the intake systems with and without a resonator including pressure and velocity distribution is conducted with the software Star-CCM+. The simulation results indicate that the air pressure drop of the intake system with a resonator is slightly higher than that of the intake system without a resonator but it is still relatively low compared with that of the entire intake system. What is more, it is also noted that the curvature structure and diameter of the pipes have a great effect on the pressure drop as well as flow uniformity. Besides, these key influence factors should be taken into consideration in the optimal design of the intake system. Simultaneously, relevant improvement measures are proposed as well in this work.
