- [NACA 0012 Airfoil](https://help.sim-flow.com/validation/naca-0012-airfoil): In this article, we will demonstrate that SimFlow is a comprehensive CFD tool that allows for very accurate modeling of the airfoils by NACA 0012 profile analysis and comparison with experimental data.

- [Natural convection in a cavity](https://help.sim-flow.com/validation/natural-convection): In this article, we will conduct a numerical simulation of a rectangular cavity between two vertical walls with a temperature difference.

- [Wave Impact in a Rectangular Tank](https://help.sim-flow.com/validation/wave-impact): In this article, we will validate SimFlow against a wave impact problem in a rectangular narrow tank.

- [Wind Analysis - Buildings](https://help.sim-flow.com/validation/wind-analysis-buildings): Validation of SimFlow simulation accuracy for pedestrian wind comfort assessment.

- [Sod Shock Tube Problem](https://help.sim-flow.com/validation/sod-shock): Sod shock tube problem as a validation case of a compressible solver.

- [Buice-Eaton 2D diffuser](https://help.sim-flow.com/validation/buice-eaton-2d-diffuser): Validation case of an asymmetric two-dimensional diffuser known as the Buice-Eaton 2D diffuser.

- [(CHT) Conjugate Heat Transfer - Pipe](https://help.sim-flow.com/validation/heat-transfer-at-pipe-CHT): In this article, we validate SimFlow’s Conjugate Heat Transfer (CHT) solver on flow through a heated pipe, comparing Nusselt numbers for free and forced convection with reference data.
