ΜΕΤΑΒΑΤΙΚΗ ΚΑΤΑΣΤΑΣΗ ΛΕΙΤΟΥΡΓΙΑΣ ΟΞΕΙΔΩΤΙΚΗΣ ΠΑΓΙΔΑΣ ΣΩΜΑΤΙΔΙΩΝ ΚΑΥΣΑΕΡΙΟΥ ΚΙΝΗΤΗΡΩΝ DIESEL
A MATHEMATICAL MODEL FOR THE SIMULATION OF THE OPERATIONAL CHARACTERISTICS OF THE TRAP DURING TRANSIENT OPERATION IS PRESENTED BASED ON TRAP INLET CONDITIONS AND TRAP HISTORY. THE MODEL INCORPORATES (A) THE FORMULATION OF FLOW CONDITIONSIN THE TRAP (B) THE FUNDAMENTAL MASS AND ENERGY BALANCE OF THE SYSTEM (C) THE FORMULATION OF THE OXIDATION PROCESS THROUGH CHEMICAL KINETICS AND (D) THE DESCRIPTION OF MASS AND HEAT TRANSFER CONDITIONS. THE MAJOR OUTPUT OF THE MODEL COMPRISE CERAMIC WALL AND EXHAUST GAS TEMPERATURE FIELDS IN THE TRAP, AS FUNCTIONSOF TIME, AS WELL AS THE LOADING LEVEL OF THE TRAP. THE APPLICATION OF THE SIMULATION MODEL CLARIFIES THE CRITICAL IMPORTANCE OF THE WALL TEMPERATURE AT TRAPOUTLET AND FORECASTS THE FAILURE PROBABILITY OF THE CERAMIC MATERIAL UNDER SPECIFIC CONDITIONS AT TRAP INLET.
