On regenerator dynamic behavior of regenerative gas turbines

Many segments lumped-parameter model of distributed regenerator is established. The process of calculation of partial differential equations is simplified. The simulation of regenerator of regenerative gas turbines is studied by numerical method under Matlab/Simulink environment. The research shows that the time-constant of regenerator is very big. The heat inertia is an important factor affecting stability of system balance, and can not be neglected in the simulation of regenerative gas turbines. The dynamic behaviors of regenerator will have important indicative effect on the controlling and operating of regenerative gas turbines.
