Summary and Research Objectives:

1. We are performing Direct Numerical Simulation (DNS) of supersonic zero-pressure gradient (ZPG) turbulent spatially-developing boundary layers at a Mach number of 2.5 and at the incompressible regime, as well.
2. The extensive information supplied by DNS is used to evaluate the compressibility effects on turbulent coherent structures via Two-Point Correlations (TPC) of flow fluctuations.
3. The data gathered from the DNS is converted into 3D virtual objects to achieve a more immersive glance. Virtual Reality and Augmented Reality is used for our Virtual Wind Tunnel and FlowVisXR in-house mobile application.

Highlights of Approach:

1. Highly scalable finite-element flow solver PHASTA.
2. Dynamic Multi-scale Approach (DMA) for turbulent inflow generation.
