ABSTRACT
In this study, the 3D hydrodynamic numerical model is established on the basis of the Reynolds equation and the turbulent flow equation. We use hydrodynamic pressure with discrete model equations in combination with finite volume and finite difference. The hierarchical grid system is suitable and efficient with a planar unstructured grid. We examine the developed 3D model with the help of different examples of analytic solution and measured data, and inspect the capability of the model to handle complex boundaries and the practicability of the flow-field simulation program in combination with practical engineering. Both the examples and practical engineering reveal the accuracy of model calculation results.
