SINOPSIS

Large Eddy Simulation (LES) results of thermal mixing in both circular and square T-junction configurations at high Reynolds number (~105) are reported in this work. The circular configuration was studied at the Alvkarleby Laboratory, Vattenfall R&D. The test rig consists of a horizontal pipe for the cold water flow and a vertically oriented pipe for the hot water flow. The square T-junction configuration with different channel sizes was studied experimentally at the Department of Mechanical Engineering of Mie University, Japan. The Vattenfall case was selected as a benchmark by OECD held in Washington DC in 2010; the second case was selected as a benchmark for thermal mixing in the ERCOFTAC Workshop held in EDF Chatou, France, 2011. Large-Eddy and URANS simulations were performed with the code TransAT©. The comparison shows excellent agreement between LES and the data.
