Diffusion Behavior of a Forced Plume Discharged in the Horizontal Direction

Abstract

The diffusion behavior of a forced plume discharged in the horizontal direction was investigated both experimentally and numerically. Velocity and temperature fluctuations in the plume were measured by FLV and thermocouple, respectively. The diffusion behavior was primary classified into two types, based on the effect of the bottom. In each case, a three-dimensional turbulent closure model (κ-ε model ) was applied to quantitatively simulate the behavior of the forced plume. The performance of the three-dimensional model was evaluated by the comparison of the numerical results with experimental measurements.
