Low-cost Schlieren system for flow visualization in transparent media in the wind sector
The Schlieren technique is frequently used for qualitative visualization of flow around an object. Temperature and density change can also be obtained with this technique.

| Sumario: | The Schlieren technique is frequently used for qualitative visualization of flow around an object. Temperature and density change can also be obtained with this technique. In this project, the aim was to develop a low-cost Schlieren system starting from easily available materials and commercial equipment. Cell phone holders were used as supports to position the concave mirrors. A light-emitting diode (LED) lamp was used as the illumination source, while a knife, a condenser lens, and printed parts in PLA (polylactic acid) plastic were key to the prototype development. Preliminary results showed an effect with limited visual perception due to the low temperature change in the objects under examination. In later experiments, qualitative visualization with a better degree of visual perception was observed due to the higher temperature range reached in the test. The images that were obtained were satisfactory and they allowed validation of the prototype development. Its main application points to the visualization of transparent flows that are formed in the airfoil of a wind turbine blade. |
