NACA 0012 Airfoil (Compressible Flow) CFD Simulation, ANSYS Fluent Tutorial

This simulation is about NACA 0012 airfoil via ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

In general, the airfoil is the same as the plane’s wing cross-section, wind turbine blade, helicopter, and so on. However, it should be noted that different airfoils can be used to construct an aircraft wing, and the choice of airfoil type in different applications depends on the aerodynamic characteristics.

Geometric defining parameters include chord line, angle of attack, leading edge, and trailing edge. The direction of the airflow into the airfoil is defined by the angle of attack (the angle between the chord and the horizontal direction of the airflow velocity).

In the present case, the attack angle is 5 degrees; thus, the horizontal component of the airflow direction is defined as 0.996 (cos5), and the vertical component is equal to 0.087 (sin5).

This project aims to investigate the airflow behavior and the pressure distribution around the airfoil and study the drag and lift forces.

We design the geometry of the present model by Design Modeler software. We mesh the model with ANSYS Meshing software. The model mesh is structured, and 35000 cells have been created.

Airfoil Methodology

In this simulation, the density-based solver is performed because the airflow is considered compressible.

Defining the Mach number in the boundary conditions is necessary for compressible flows. The Mach number is equal to the ratio of the speed of an object in a fluid to the sound speed in the same fluid in which that object moves.

For example, the sound speed in the air with a temperature of 25 degrees Celsius is 343 meters per second.

In general, the simulation of an airfoil requires the definition of a far-field boundary condition, and therefore the Mach number for the flow field must be defined, the value of which in the present case is 0.6.

Airfoil Conclusion

After simulation, we obtain two-dimensional contours of pressure, velocity, temperature, density, and Mach number, as well as two-dimensional streamlines.

The results show that at the leading edge of the airfoil, the highest pressure appears, caused by the airflow’s direct contact with the airfoil’s leading edge.

The structure of the airfoil is such that the airflow on its upper surface faces the greatest pressure drop. This pressure difference between the top and bottom of the airfoil body causes the upward movement of the wing.

Also, the velocity changes are in perfect accordance with the pressure distribution. Where there is the greatest pressure, the least velocity appears, and vice versa.

    The results for this NACA 0012 airfoil simulation sound thorough. The use of a structured mesh with 35,000 cells surely helped in capturing the precise aerodynamic features. The simulation parameters, including the angle of attack and Mach number settings, seem meticulously chosen to reflect realistic flying conditions. Comprehending how the pressure distribution affects the lift is fascinating, and the density-based solver must have provided accurate compressibility effects. Furthermore, the detail on the pressure-induced velocity changes reaffirms confidence in the quality of these CFD findings.

    NACA 0012 Airfoil CFD simulation explained how the drag and lift forces on the airfoil were studied. Could you please tell me how accurate the results of the simulation were compared to physical wind tunnel tests?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Regarding the accuracy of the results from our NACA 0012 Airfoil CFD simulation compared to wind tunnel tests, the simulation framework in ANSYS Fluent is designed to replicate physical phenomena with high fidelity. By accurately defining the airfoil geometry, boundary conditions, and physical properties of the flow, we strive to ensure that our CFD results closely match experimental data. Although some differences between simulation and real-world testing can occur due to simplifications and model assumptions, we calibrate our models based on benchmarks and available literature to provide results that are as accurate as possible within the constraints of computational resources.
