This paper studies the impingement on ground of a submerged round water jet of diameter 0.02 m at angles of 15, 30, 45, 60, 75 and 90 degree by numerical simulation. Reynolds number at jet exit is 23,400 and the height between the exit of jet pipe and impingement plane is 0.06m. For numerical simulation, Reynolds-Averaged Navier-Stokes (RANS) equations are solved with realizable k-ε and Wray-Agarwal (WA) turbulence models using the commercial CFD solver ANSYS FLUENT. Pre-and post-processing are done by ICEM-CFD, CFD-POST and Origin Lab. Results from numerical simulations are compared with the experimental data and show that both turbulence models obtain results in reasonably good agreement with the experimental data, while WA model shows some improvement over the realizable k-ε model. Differences between the numerical and experimental results are analyzed.
