2  Flat Plate Boundary Layer

Laminar and turbulent flat-plate boundary-layer verification, across solver tracks

The flat plate is Wake CFD’s baseline boundary-layer verification geometry — the same physical setup family (Blasius/Pohlhausen similarity for laminar flow, NASA TMR for turbulent SA/SST) is run across solver tracks so results can be compared directly, independent of laminar/turbulent regime.

Solver	Regime	Case	Compared against
DBNS	Laminar	2D Laminar Flat-Plate Boundary Layer — Blasius & Pohlhausen Verification	Blasius/Pohlhausen similarity solutions
DBNS	Turbulent (SA)	2D Turbulent Flat-Plate Boundary Layer — NASA TMR SA Verification	NASA TMR (CFL3D/FUN3D)
DBNS	Turbulent (SST)	2D Turbulent Flat-Plate Boundary Layer — NASA TMR SST Verification	NASA TMR (CFL3D/FUN3D)
DBNS	Turbulent (SA), M=2 and M=5	2D Turbulent Flat-Plate Boundary Layer, M=2 and M=5 — NASA TMR SA Verification	van Driest II / I theory, CFL3D SA (NASA TMR)
PBNS	Laminar	3D Laminar Flat-Plate Boundary Layer — PBNS Blasius Verification	Blasius similarity solution
FR	Laminar	2D Laminar Flat-Plate Boundary Layer — FR Blasius Verification	Blasius similarity solution

All six published cases are verification cases (see How Cases Are Classified): each compares against a computed reference — an exact similarity solution, or independent CFD codes, or van Driest theory — rather than experimental data.
