| Abstract:In order to solve the deformation of marine diesel engine SCR reactor in operation due to the high temperature of exhaust gas, thermal-structural coupling analysis of the reactor was carried out.Based on the analysis results, the optimal design programme of this reactor was put forward. The results show that the optimal programme can effectively reduce the deformation of the reactor, and the equivalent stress has also been reduced. |
