Design Optimization of Catalytic Converter to Achieve Limited Back Pressure in Diesel Engine by using CFD

Abstract

Presently a days the a dangerous atmospheric devation and air contamination are huge issue on the planet. The 70% of air contamination is because of outflows from an inner burning motor. The unsafe gasses like , NOX CO, unburned HC and particulate matter builds the a worldwide temperature alteration, so exhaust system assumes an imperative part in diminishing destructive gasses, however the nearness of exhaust system expands the fumes back weight because of this the volumetric productivity will abatement and fuel utilization is higher. So examination of exhaust system is imperative.

 

The uncommon earth metals now utilized as impetus to lessen NOX are excessive and infrequently accessible. The lack and popularity of present impetus materials require the requirement for discovering the choices. Among all other particulate channel materials, weaved steel wire network material is chosen as channel materials in this paper. Through Computational Fluid Dynamics (CFD) examination, different models with various wire network lattice size blends were mimicked utilizing the suitable limit conditions. The correlation of back weight of various exhaust system models is made in this paper.
