概要	By making use of Laser-Doppler-Velocimeter, Reynolds shear stress and three components of Reynolds normal stresses have been measured in an axi-symmetrical confined jet. Additionally, numerical computation have been made with k-ε two-equation model of turbulence, full Reynolds stress model and algebraic Reynolds stress model. The turbulence near the wall has been confirmed to be more intensive in the recirculating flow region than around the flow reattachment point. The result gives a partial proof for the previously reported conjecture on the physical background for the spatial separation between the maximum Nusselt number position and the flow reattachment point. The measured turbulence quantities have also been discussed from other view points. The Reynolds stress model shows rather poor applicability to the presently studied type of partially recirculating turbulent flow. The k-ε two-equation model gives reasonable results.
