Development of Forced Hydraulic Jumps: Particle Image Velocimetry and Mesh-Free Modeling

摘要

The current study aims at the internal flow field and the corresponding phenomena in the developing stage of forced hydraulic jumps It consists of experimental and numerical investigations A series of experiments with various Froude number were performed by adjusting the inclination angle of the channel A nonintrusive measuring technique Particle Image Velocimetry (PIV) was applied in the experiments Numerically Weakly-Compressible Moving Particle Semi-implicit (WC-MPS) method coupled with the Sub-particle-scale turbulence model was employed to reproduce the flow phenomena The simulation results for both flow surface profiles and velocity distributions at different sections were compared to the experimental data from the reference and the current study Flow phenomena showed good agreement with the numerical simulation results Finally the results from both experiments and simulation provided a detailed examination of the flow field during the developing stages of forced hydraulic jumps
