CFD modelling of entropy generation in turbulent pipe flow: Effects of temperature difference and swirl intensity

- The effects of swirl number and temperature difference on entropy generation in pipe flow were investigated.
- A CFD model was established and validated with experimental LDV measurements.
- The CFD model was used to simulate 77 cases representing 0≤Sn≤0.454 and 0≤ΔT≤60
- Matlab was used to establish empirical correlations based on the CFD results.
- The empirical correlations predict entropy generation and Bejan number as functions of Sn and ΔT
