Numerical simulation of water flow around ship with screw propeller

This paper outlines development of method for simulation of complex fluid flows having arbitrary motion of free surfaces. The method is based on rectangular grid with dynamic local grid adaptation. For approximation of a curvilinear computational domain boundaries and a free surface the subgrid geometry resolution method is used. The free surface tracking is provided by VOF method.

Numerical Simulation of Water Flow around

Using this approach a fluid flow around ship hull is simulated. Calculation is made with and without taking into account screw propeller. Results are compared with experiment.

In this paper we offer an extension of VOF approach (Hirt, Nichols, 1981). It is realized in FlowVision CFD code.
