(2) Training of all ship / engine operation modes
(3) Full application of computer graphics
(4) Full application of computer network design
5.1 PRECISE SIMULATION MODEL
The simulator has precise simulation model as follows.
(1) Precise diesel engine propulsion plant model
(2) Real time basis mass flow balance calculation
(3) Real time basis heat balance calculation
For the simulation calculation of temperature, pressure, level etc. of the plant model and piping system model
(4) Real time basis diesel engine combustion calculation
For the combustion analysis of Pmax, Pcomp, P-θ(dp/dθ) indication of the diesel engine model (shown in Fig. 10)
More than 100,000 process variables, status variables, parameters, constants, etc. are used in the simulation system and those can be varied to know / study what happens if those values are changed.
