- Abstract
The need for comparative studies between experimental and numerical results exists due to the long lasting necessity for verification and validation. Accordingly, background oriented schlieren (BOS) provides a unique opportunity to perform non-intrusive quantification of density varying flows by means of an inexpensive and simple setup. As the optical flow based image processing algorithms are shown to mitigate the lower resolution and sensitivity of BOS, it is utilized to conduct an analysis of the capabilities of different computational configurations for the identification of key supersonic flow features. While experiments are conducted over a case of a 10◦ wedge model exposed to Mach 3.5 supersonic flow conditions, the... (More)
The need for comparative studies between experimental and numerical results exists due to the long lasting necessity for verification and validation. Accordingly, background oriented schlieren (BOS) provides a unique opportunity to perform non-intrusive quantification of density varying flows by means of an inexpensive and simple setup. As the optical flow based image processing algorithms are shown to mitigate the lower resolution and sensitivity of BOS, it is utilized to conduct an analysis of the capabilities of different computational configurations for the identification of key supersonic flow features. While experiments are conducted over a case of a 10◦ wedge model exposed to Mach 3.5 supersonic flow conditions, the numerical simulations are performed by means of two main turbulence treatment schemes of URANS and LES employing k-ω SST turbulence and LDKM sub-grid scale (SGS) models respectively. Accordingly, physical orientations and intensities of the captured flow features, and the respective physical, optical and numerical features driven by the specifications of the experimental and numerical configurations are detailed.
