Abstract

Experimental data are obtained about a structure of turbulent flow within a circular-section tube for stationary and hydrodynamically non-stationary gas flow regimes. Heat-transfer and hydraulic resistance coefficients are computed for non-stationary air flows using these data. The results can be used for engineering analysis of high thermal-stressed structural elements.
