Abstract

The two-dimensional flow fields in the pipe junctions with roundness at the upstream edge and the upstream and downstream edges of the lateral entrance in the turbulent flow were solved numerically by using the k-ε turbulence model. The mean flow in the real pipe junctions was observed by means of a flow visualization technique. The computed results referred to the mean flow were compared with the experimental ones.
