Boat propeller

Bootspropeller FE
The objective of this project was to determine the thrust and power consumption of a two-bladed boat propeller at various speeds and inflow velocities.

During meshing, special attention was paid to the quality of the cells near the propeller surface.

Starting from the cross-linked surface, ten prism cell layers were built up (see image above, detail wing root) to better resolve velocity gradients to the wall.

In the figures, velocity vectors and pressure distribution on the propeller and hub are shown in two planes (parallel to the inflow direction, near the wing root).

With the findings from the flow simulation, the propeller can be operated in an optimum speed range. The propeller was additionally recalculated with the self-developed panel code P4. The results showed a very good agreement…
