Abstract

Diesel engines emit sparks as a result of breaking and burning of carbon deposition inside engine cylinders and exhaust system. Spark Arrestor plays a critical role in impeding the embers emission as it arrests and traps the embers and the sparks inside it. The objective of this paper is to Design, Model, and Simulate Spark Arrestors in terms of Acoustic Performance. Two models of Spark Arrestors were selected; one Commercial and a newly developed centrifugal Spark Arrestor. The Acoustics design and Simulations were performed using two port theory where, the Spark Arrestor models are limited to the plane wave range. These models were implemented in SIDLAB software for simulating the propagation of low frequency Sound and air flow in Ducts. The theoretical modeling for the two models was shown to be matched with the experimental verification in terms of transmission loss within 92% to 98%, and in terms of pressure drop within 86% to 99%.
