Comprehensive design and simulation study of ammonia fuel supply and auxiliary system

Abstract As humanity keeps exploring new energy sources, ammonia fuel is gradually coming to the public’s attention. Considering the energy supply requirements of ships, this paper utilizes Modelica software to design and simulate the ammonia fuel supply and auxiliary systems for ships. Simulation models for supply pumps, heat exchangers, and valves have been designed, and PID control has been applied to the pump model and a portion of the valve model, thus forming a system model. Simulation tests were carried out on this system model under actual operational conditions, and it was discovered that the model fulfils the energy supply requirements of ships.
