Abstract：Water jet has wide applications in industrial production and holds significant research value.This paper employed a numerical simulation method using CFD software to simulate and analyze the flow field of a water jet.A simplified two-dimensional axisymmetric model with a circular nozzle was established,employing a glycerin-water solution as the fluid medium the turbulence model based on SST-SAS model was utilized,and the results were compared with experimental data.The following conclusions were drawn:the k-ε turbulence model is inadequate for simulating the flow characteristics of low Reynolds number region in water jet.In contrast,the SAS turbulence model exhibited good agreement between calculated values and experimental results at different positions,demonstrating its capability to accurately simulate the flow field of low Reynolds number region in water jet;this study provides a solid foundation for further research on the impact of factors such as impact height,nozzle shape,and Reynolds number on the flow field characteristics in water jet.
