Investigating the effect of in-cylinder gas compositions on sulfuric acid formation and condensation using CFD modeling under large two-stroke marine engine-like conditions
Abstract
A computational fluid dynamic simulation is utilized to model the formation and condensation of sulfuric acid (H<sub>2</sub>SO<sub>4</sub>) under large two-stroke marine diesel engine like conditions. A skeletal chemical mechanism coupled with a sulfur subset is used to simulate the combustion process and the formation of sulfur oxides (SO<sub>x</sub>) and H<sub>2</sub>SO<sub>4</sub>. A fluid film model coupled with the Eulerian in-cylinder gas phase describes the condensation of H<sub>2</sub>SO<sub>4</sub>. Exhaust gas recirculation (EGR) is a well-known method to decrease the nitrogen oxides (NO<sub>x</sub>) emission. However, one of the sideeffects of EGR may be an increase in sulfuric acid condensation which leads to cold corrosion of liner. In this study the initial in-cylinder gas compositions are varied to imitate different EGR compositions (wet and dry) and the associated effects on the formation and condensation of H<sub>2</sub>SO<sub>4 </sub>are investigated. It is found that the amount of SO<sub>x</sub> formation is similar for these two kinds of EGR which is lower than base case (without EGR). The interesting finding is that the H<sub>2</sub>SO<sub>4</sub> vapor formation for wet and dry EGR is higher and lower than the base case, respectively. The current CFD results show that applying EGR does not increase theH<sub>2</sub>SO<sub>4</sub> condensation.
