CFD Studies Drone

Motivation

To simulate airflow around a drone. First the real propellers were 3D scanned

Scanning the propeller

After scanning the propeller it is possible to create a CAD model

The 3D CAD model can then be generated. Several millions elements are used to mesh the propeller

Creating a mesh

From the 3D model it is possible to create a mesh where the propeller is divided into several elements that can be calculated.

The air around the propellers are also meshed

Simulation Results

From this it is possible to simulate the air around the propellers and the drone. The air speed can then be visualized and results can be seen

Testing Results

Slow motion movies of the drone flying in smoke were used to compare the studies.

We also did advanced measuring studies using transversing hot wires. But these results I can not share.
