Modeling with Fault Integration of the Cooling and the Lubricating Systems in Marine Diesel Engine: Experimental validation
Abstract In this paper, physical models for the cooling and the lubricating systems for marine diesel engine have been developed. The main purpose of this modeling is to integrate some possible faults that may be produced, and then to analyze their effects on the overall marine diesel engine during operation. Faults may appear in the model as the variation of some parameters. The importance of this study is to prepare an important data base for the fault diagnosis and prognosis strategies that may be applied on Diesel engines. Experimentations on Marine Diesel engine test bench have been used for the validation of the proposed model.
In this paper we study the dynamics of the Kepler-36 exoplanetary system. The two planets are engaged in the mean-motion resonance of 6:7. The dynamical stability of this system has been studied by numerical methods using a Lie-integrator and calculating the Lyapunov characteristic indicator (LCI) and maximum eccentricity (ME). We studied the stability of the system, the stability of another planet, and the stability of satellites belonging to the known planets. The possibility of trojans were also studied using the massless approximation. The tidal perturbations were neglected although they can become significant in some cases.
