Dynamic behavior of the gas turbine engine regenerator with complanar channels

Аннотация

This paper expounds a technique for calculating unsteady gas temperatures, air and heat transfer elements of the corrugated plate of a recuperative heat exchanger with complanar channels for start and shut-off modes of the regenerative turbine engine. Under consideration are the distribution of thermal stresses in the plate, heat exchanger service life under stationary conditions, and the allowable number of dynamic “start–shut-off” cycles.
