Abstract

A plane, turbulent, nonbuoyant, vertical jet in shallow water is simulated numerically using a three-dimensional computation model employing standard 𝑘 - 𝜀 and renormalized group 𝑘 - 𝜀 turbulent closure schemes. Existing data of mean and turbulent flow quantities, measured using laser Doppler velocimeter, are used to assess the two turbulent closure schemes. Comparisons between the measured and simulated flow field data are made in the free jet region, within the zone of surface impingement, and in the zone of horizontal jets at the surface. The results show that the standard 𝑘 - 𝜀 scheme performs equally well and in some areas better than the more complicated renormalized group 𝑘 - 𝜀 scheme in simulating the mean and turbulent flow quantities in this case.
