Static research of flow in rotor channels of the regenerator
چکیده انگلیسی
One demonstrates here the results of static experiments which suggest the pulsating flow in rotating channels of the rotor of heat regenerators occurs. Electrolytic technique was used to measure distribution of the mass transfer coefficient for one of many straight, round, radial ducts of the rotor for different angle positions at mean Reynolds number as a parameter. The use of the Chilton-Colburn analogy made it possible to state the angle-distribution of flow-velocity. The Reynolds number deviation was about ±30% in comparison with its mean value which suggests that the phenomenon should be taken into account in formulating the models of rotary heat exchangers. An equality - approximately - of the mean velocity of an out-gassed electrolyte in the opposite ducts of the rotor of the model, working in a closed hydraulic system, was stated which was justified theoretically for one-dimensional flow.
