Detecting Local Surface Defects on Rotor Blades

There can be various types of surface disturbances (additive or subtractive) with different dimensions on rotor blades. Have you ever wondered whether there is a relationship between the flow downstream of a disturbance and the parameters of the disturbance itself?

One approach to investigate this relationship is to measure the flow behind the disturbance in a wind tunnel experiment. Infrared thermography (IRT) provides a method for indirect flow measurement.

Possible Tasks

• Conduct wind tunnel experiments to validate the measurements and to quantify the sensitivity of infrared thermography (IRT) to the disturbance parameters (height, diameter, position, and type), assuming cylindrical-shaped disturbances.
• Evaluate the recorded thermographic images by generating averaged images and analyzing their temporal evolution in order to identify characteristic parameters of the flow downstream of the disturbance.
