This paper presents some results of the numerical study of hydrodynamic parameters and heat transfer in a periodic gas flow in a circular pipe in which the flow oscilations were generated by the pressure variation at one of the pipe ends. The considered case was selected because it represents an experimentally well documented configuration of engineering interest. In addition it may serve as a suitable geometry for testing the applicabilities of different numerical schemes for solving the mathematical model.
The comparison of the experimental and numerical results demontrated a satisfactory agreement. The significant augmentation of the heat transfer coefficient was especially noticable in the resonant conditions, when the incitement frequencies of the flow pulsation corresponded to the duct natural frequencies.
