To enhance the heat transfer inside the circular tube, a vane swirler is used to improve the Nusselt number. Numerical modeling was performed using Ansys Fluent CFD software by employing K- \(\varepsilon\) turbulence model with the SIMPLE algorithm. The CFD simulation results are compared with experimental data and an 8.41% maximum error is obtained. Further, the impact of employing two swirlers on the improvement of heat transfer was investigated, and it was found that at Reynolds number 30,000 the heat transfer rate is increased by 127%, 95.99%, and 93.505 at different positions.

摘要

To enhance the heat transfer inside the circular tube, a vane swirler is used to improve the Nusselt number. Numerical modeling was performed using Ansys Fluent CFD software by employing K- \(\varepsilon\) turbulence model with the SIMPLE algorithm. The CFD simulation results are compared with experimental data and an 8.41% maximum error is obtained. Further, the impact of employing two swirlers on the improvement of heat transfer was investigated, and it was found that at Reynolds number 30,000 the heat transfer rate is increased by 127%, 95.99%, and 93.505 at different positions.
