One Stage

The influence of geometric (length, diameter and wall thickness of a unit equivalent channel of the nozzle), thermophysical (density and heat capacity of the nozzle material) and operating parameters (air flow through the regenerator and the time of one stage of accumulation / regeneration of thermal energy) on the thermal efficiency of stationary switching regenerative heat exchangers was studied . It was revealed that by varying the length and diameter of the channel and air flow, it is possible to increase thermal efficiency up to 10%. It was found that the wall thickness of a single channel, the density and heat capacity of the material of the nozzle, as well as the time of one stage, slightly aff ect the thermal efficiency of the regenerative heat exchanger.
