Abstract

The flow mechanisms in a pipe junction in the turbulent flow were studied numerically by using a turbulence model with two different equations-one for the kinetic energy of turbulence, k, and the other for its dissipation rate, ε. The turbulent flow field in an actual pipe junction was also studied experimentally with a model by a flow visualization technique. The results referred to the mean flow obtained by computation and experimentation are compared and the flow mechanisms are discussed theoretically and experimentally.
