Design of Suitable Aperture Shape for Optical Measurement Methods in Experimental Chamber

This article deals with the experimental chamber preparation, on which shockwaves, besides other measurements, will be observed using the Schlieren optic method. Because of this reason, the replaceable aperture will be used, which will be placed against the center of the observation window. The design of the optimal aperture shape was solved using mathematical – physics analysis in the Ansys Fluent system and the results will be compared with the results obtained from the experimental measurements.
