Title: Supersonic Internal Flow Simulation: Achieving Solver Stability Beyond Classical Benchmarks

[RonaldPittman]

Hello everyone,

I am thrilled to share the results of my recent CFD simulation, where I successfully modeled high-curvature internal flow reaching supersonic speeds of 592 m/s with a pressure differential exceeding 560 MPa.

This simulation breakthrough demonstrates:

• Solver Stability: Maintaining numerical stability with extreme Mach numbers and significantly steep pressure gradients, conditions that would typically cause standard CFD models to fail.

• Boundary Layer Analysis: Mapping the exact point of boundary layer separation under high-curvature, supersonic internal flows that exceed benchmarks set by classical aeronautical models.

I believe this work showcases boundary-breaking advances in applying CFD models to extreme situations.

I would love feedback or discussions on:

1. Are there additional validation methods or edge cases I should consider?

2. Thoughts on numerical diffusion under these extreme gradients—has anyone faced similar conditions?

3. Could these results be generalized to external supersonic flows, or are there considerations unique to internal geometries?

Looking forward to engaging with the community!
