Description

Turbulent air flow in a central channel of heated 37-rod bundle with triangular array. The case presents significant differences with the standard flow in a circular tube. Moreover there is the presence of a large-scale periodic fluctuation of velocity and temperature in the gap region between two adjacent rod. These fluctuations are responsible of the exchange of momentum and energy between sub-channels. The secondary flow has a minor role in this exchange process.
