The study contributes to a better understanding of the thermal mixing phenomena that occur at T-junctions and emphasizes the significance of the inlet velocity profile in affecting the dynamic and thermal characteristics of the flow. Ansys CFX version 19.1 was used to examine the dynamic and thermal behavior of turbulent flow in a T-junction, employing two turbulence models: URANS (SST) and LES with a power law velocity profile. The obtained results offer useful information for creating suitable geometric layouts and optimizing pipe systems. The study hypotheses were validated by comparing the obtained results with the experimental data from the Vattenfall facility. The velocity and temperature fields were calculated at multiple locations downstream of the junction. As will be shown in the results section, there was a good agreement between simulation predictions and experimental data.
