Abstract: The thermodynamic calculation software of Intercooled-Cycle gas turbine was developed to observe the impacts that the environmental parameters and cold degrees of intercooler produce quantitatively on this marine engine performance. And then, the mathematical model of intercooled-cycle gas turbine was established and the relative non-linear simulation model was also built based on MATLAB/SIMULINK to further study on flow parameters optimisation for marine gas turbine intercooler. At last, under a given structure size of intercooler, the impact of different liquid-side flow parameters on the intercooler system performance was analysed based on simulation model. The simulation experimental results show that the increase in glycol-water solution flow rate and seawater flow rate can improve the performance of the intercooled-cycle gas turbine to a degree, but the rational flow rates should be chosen according to the atmospheric condition and seawater temperature, and the optimal regulation rule was got.

Keywords: simulation; optimal analysis; flow parameters; parameter optimisation; marine gas turbines; intercooler systems; thermodynamics; mathematical modelling; glycol-water flow rate; seawater flow rate; atmospheric conditions; seawater temperature.
