The geometry used for this case can be seen below:
It is a two-blade propeller represented using its dimensions in inches. This APC 11×5.5E model is an 11-inch diameter propeller with a pitch of 5.5 inches/revolution used on small UAVs and model aircrafts.
The Standard mesheralgorithm with tetrahedral and hexahedral cells was used to generate the mesh. Multiple meshes with incrementally increasing refinement were generated in parallel using the automatic meshing functionality.
For each run, the thrust and power coefficients were calculated and plotted below:
A mesh sensitivity analysis has been carried out monitoring the y+ maximum values while using full resolution wall treatment with the standard mesher:
Number of cells/nodes
4.3M cells, 1.4M nodes
6.1M cells, 2.2M nodes
13.4M cells, 4.1M nodes
Table 1: The characteristics of the mesh sensitivity analysis with respect to the maximum y+ values for 6473 RPM, which is the highest input tested in this case.
