NUMERICAL AND EXPERIMENTAL-STUDY OF MIXED AND FORCED-CONVECTION IN A JUNCTION

This paper presents a theoretical and experimental investigation of th e laminar steady 2D-mixing flow in a junction. The numerical method de veloped by Gosman et al. has been applied to derive velocities and tem peratures profiles in the mixing zone. The effects of the angle betwee n the two branches of the junction and the air-flow rate upon the stru cture flow are analysed, for both forced and mixed convection cases. T he experimental procedure is based upon a flow visualization technique and L.D.V. velocity measurements: a reasonably good agreement between theoretical and experimental results is found.
