Continous Computer Simulation Model of the Marine Gas Turbine

Simulation Modelling, together with System Dynamics and intensive use of modern digital computer, which mean massive application, today very inexpensive and in the same time very powerful personal computer (PC-a), is one of the most suitable and effective scientific way for investigation of the dynamics behaviour of non-linear and complex: natural, technical and organization systems. The methodology of System Dynamics (Prof dr. J. Forrester – MIT), e.g. relatively new scientific discipline, in former educational and designer practice showed its efficiency in practice as very suitable means for solving the problems of management, of behaviour, of sensibility, of flexibility and sensibility of behaviour dynamics of different systems and processes. System-dynamics computer simulation methodology have been used from 1991 to 2003 for modelling of dynamics behaviour of the large number of non-linear ship electrical, thermo-dynamical, hydraulically, mechanical and pneumatically systems. This methodology is used by students as a material for graduate these at Maritime faculty Split. Investigation of behaviour dynamics of the ship propulsion system, as one of the complex, dynamics, non-linear and technical system, requires application of the most effective modelling methods. The aim of this paper is to show the efficiency of the application of the System Dynamics Simulation Modelling in investigation of behaviour dynamics, one of the complex marine system and process i.e. "gas – turbine". Twin shaft gas turbine shall be presented with mental-verbal, structural and mathematical-computing modules, and will simulate working process of turbine.
