Convergent-divergent nozzle contour

Convergent-divergent nozzle: compressible internal-flow behavior and shock-sensitive interpretation.

Why this is one project

  • Scan speed: one card communicates breadth faster than seven separate cards.
  • Technical signal stays strong: the page still proves range across major CFD regimes.
  • Detail control: enough evidence to build trust, without publishing every setup decision online.

What this consolidated track covers

  • Internal flow: convergent-divergent nozzle.
  • Bioflow-style canonical case: 2D artery stenosis.
  • External aerodynamic regimes: sub/transonic wing and airfoil contexts.
  • High-speed compressible regime: supersonic wedge.
  • Rotating-flow context: VAWT MRF workflow.

Case index

  • Convergent-divergent nozzle: Compressible internal-flow trend behavior with regime transitions. Key output: shock-sensitive field interpretation across nozzle sections.
  • 2D artery stenosis: Flow acceleration and pressure-drop behavior in narrowed passage. Key output: velocity/pressure trend consistency under constrained geometry.
  • Transonic NACA0012: Transonic airfoil flow with shock-related response. Key output: regime-aware interpretation of field transitions near the airfoil.
  • Forced convection flat plate: Boundary-layer-focused setup and near-wall behavior trends. Key output: correlation-minded wall behavior checks and profile tracking.
  • Vertical-axis wind turbine (MRF): Rotating-flow context and wake behavior under turbine operation. Key output: flow-field structure useful for load/performance interpretation.
  • ONERA M6 wing (transonic): 3D external-aero transonic behavior. Key output: shock/flow-feature mapping across wing surfaces.
  • Supersonic wedge: High-speed compressible structure capture. Key output: stable shock-pattern interpretation for benchmark comparison.

Case notes

Nozzle flow case

  • Compact internal-flow benchmark to validate compressible setup discipline.
  • Useful for comparing contour behavior and feature placement trends.

Artery stenosis case

  • Demonstrates how geometric constriction shifts local acceleration and pressure losses.
  • Shows cross-domain CFD reasoning beyond only external aero.

Transonic NACA0012 case

  • Used for transonic regime interpretation near streamlined geometry.
  • Helps communicate shock-related trend awareness.

Forced-convection flat plate case

  • Boundary-layer-oriented benchmark reinforcing near-wall setup habits.
  • Supports correlation-minded reporting consistency.

VAWT MRF case

  • Rotating-flow context for wake and region-specific flow interpretation.
  • Complements fixed-geometry benchmarks with turbine-style physics.

ONERA M6 transonic wing case

  • Extends airfoil-level interpretation into a 3D wing-level context.
  • Emphasizes large-scale transonic flow-structure reading.

Supersonic wedge case

  • Compact high-speed benchmark focused on shock-pattern interpretation.
  • Useful for confidence checks in compressible trend reporting.

What this demonstrates quickly

  • Ability to move between very different physics while keeping modeling discipline.
  • Verification mindset: checks are treated as part of the workflow, not an afterthought.
  • Reporting clarity: outputs are organized for decision-making, not just plot generation.
