Abstract: This article discusses thermal properties of slotted heat transfer matrix of rotary regenerators of small scale gas turbine engines (microturbines). Thermal processes in channels of slotted matrix of rotary regenerator have been predicted, the model of rotary regenerator with slotted heat transfer matrix has been analyzed. The predictions were based on finite volume software, the experiments were carried out on test rig with the regenerator model. Distribution of Nusselt criterion along the channel length as well as stabilized Nusselt criterion are presented. The influence of velocity, sizes, and temperature on stabilized Nusselt criterion has been studied. Experimental and predicted regeneration rates of rotary regenerator with slotted heat transfer matrix are given, their close correlation has been obtained.
Keywords: Heat Exchange, Microturbine, Regenerator, Convection, Nusselt Number, Experiment.
