Abstract— The behavior of the water vortex is interested in designation of turbine blade for Water Vortex Power Plant (WVPP). This study uses Xflow, a commercialize CFD code base on Lagrangian approach, which provides the details of water vortex formation without much difficulty as discretization of flow domain is not required at all. The boundary conditions of the CFD models are applied based on the experiment setup. Two conditions were investigated, with two different holes size for water discharge. The result in first condition shows the vortex height agree each other in experiment and CFD. For second condition, the final vortex height of the CFD model is different from the experiment result. As the discharge hole is getting larger, more turbulent flow has set in and causing more errors in the CFD model in predicting the water vortex formation. However, the CFD model can be improved by better turbulent modeling.
