Heat transfer of pulsating turbulent pipe flow in rolling motion

The heat transfer of turbulent pulsating flow is of vital importance in nuclear reactor thermal hydraulic analysis in ship motions. In this paper, the heat transfer behavior of turbulent pulsating flow is analyzed. The calculation results are verified with experimental data, with satisfactory agreement obtained. The effect of span-wise and transverse additional forces decreases with Reynolds number increasing and is significant in low Reynolds number. The effect of velocity oscillation period on the heat transfer is more limited than the effect of Reynolds number and oscillating velocity Reynolds number.

► We analyzed the heat transfer behavior of turbulent pulsating flow.
► The calculation results are in satisfactory agreement with experimental data.
► The effect of additional forces is significant in low Reynolds number.
