Marine GTs

This is a library of engine performance models of various types of marine gas turbines developed using the PROOSIS simulation environment. The user defines the set-up and its design point and then the model adapts components’ performance maps and other engine specific parameters (e.g. cooling bleeds) as to make the simulated engine to have the desired performance at the design point.

The operation at an off-design point is computed with the aid of the derived components’ performance maps. The model has the ability to simulate the engine’s performance from 7%-10% to 100%-105% of its design state. In all cases, the engine performance model can simulate gas turbine operation with four different fuels (two types of diesel, natural gas and methane). The emitted pollutants, NOx and CO, are predicted by the means of semi-empirical correlations.The performance models derive for the user specified operating conditions the complete engine cycle as well as overall performance parameters.
