Density contours for wedge configuration.
Snapshot
- Case type: Supersonic external compressible flow
- Primary objective: Resolve oblique-shock-driven changes behind a wedge
- Lesson basis: Ansys Innovation "Supersonic Flow Over a Wedge"
- Secondary view: Wedge vs cone contour comparison
Problem specification
- Uniform supersonic stream impinges on a wedge with a 15 degree half-angle.
- Targeted outputs from the lesson scope:
- Mach number downstream of shock
- Static and total pressure behind shock
- Shock angle
- Pressure coefficient along wedge
- Drag coefficient
Setup and method
- Followed the structured workflow from lesson sequence (problem setup through numerical results).
- Used compressible-flow post-processing to inspect shock signatures in:
- Density field
- Static pressure field
- Mach contours
- Pathline patterns
- Organized wedge and cone figures in paired sequence for direct visual comparison.
Results and interpretation
- Wedge case shows clear post-shock field shifts consistent with oblique shock behavior.
- Mach and pressure plots show distinct compressed regions near wedge surfaces.
- Density pathlines capture compression-driven flow reorganization downstream.
- Cone comparison provides an additional geometric reference for interpreting shock/field distribution.
Validation and reproducibility notes
- Validation is tied to the lesson objective: compare CFD outputs with analytical shock-based targets.
- Fixed export framing allows quick rerun comparisons without presentation drift.
- Image package is organized by variable and geometry for consistent review.
