Abstract
This paper presents both experiment and numerical simulation on Two-dimensional vertical impinging jet in cross flow. Intake pond of the cooling water system is a requisite component of thermal or nuclear power plant. But in intake pond sediment deposition is heavy. Impinging jet was equipped in a nuclear power plant in China and has a significant impact on sediment suspension. However, before this investigation, little attention has been paid to the mechanism of this application case. In response to the demands of the engineering design, started this study. Experiments are performed for different Reynolds number ratio of the jet-to-cross-flow R varying from 0.13 to 0.22. The measurement results of turbulent parameter and flow structure are obtained. Moreover the turbulent parameters play an important role on sediment transportation. As well the experiment results agree well with the calculations provided from κ - ε turbulence model.
