摘      要：A numerical simulation for urea decomposition into ammonia with static mixers was performed for marine selective catalytic *** types of mixer were considered to improve urea into ammonia conversion *** effect of each mixer such as pressure drop,particle residence time,and uniform distribution of urea water solution was investigated using three dimensional CFD *** mixer regardless of a type was improved urea *** performance could be affected by high pressure drop caused by ***,the proper mixer should be chosen in permissible level of pressure drop as well as ammonia conversion rate.
