Optimal analysis of flow parameters for marine gas turbine intercooler based on simulation model

The mathematical model of intercooled cycle gas turbine was established and the relative simulation model was also built based on MATLAB/SIMULINK. Under a given structure size of intercooler, many magnificent conclusions were drawn over the analyses of influence of different liquid side flow parameters on the intercooler system performance. The simulation experimental results show the increase of glycol water flow and seawater flow can improve the performance of intercooler, but the performance isn´t better as the flow of glycol water and seawater is larger. The rational flow rates should be chosen according to flow conditions. The influence of seawater inlet temperature on intercooler efficiency is significant and need to be considered in the optimal design.
