Equipe Energétique des Moteurs à Combustion Interne Laboratoire de Mécanique des Fluides – UMR CNRS 6598 Real-time performance simulation of marine Diesel engines for the training of Navy crews Pascal Chessé, David Chalet, Xavier Tauzia, Jean-François Hétet, Bahadir Inozu Journal of Marine Technology The Society of Naval Architects and Marine Engineers This paper presents a marine diesel engine simulation code designed for real-time performance. The main novelty is that the various equations are derived from the laws of thermodynamics, thus guaranteeing qualitatively accurate predictions and allowing for easy use with any type of engines. The code is based on the "filling and emptying" method with various simplifications to achieve real-time performance. A number of failure models were added to interface the code with a propulsion training application. This was done in order to educate crews on failure detection and the management of emergencies.
