Description
Description
In this project, steady airflow over a flapped airfoil with an attack angle equal to 12 degrees is investigated by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The present model is designed in two dimensions using Design Modeler software. The meshing of the model has been done using ANSYS Meshing software. The element number is 64731.
Flap Methodology
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps also cause an increase in drag, so they are retracted when not needed.
This project investigates steady airflow over a flapped airfoil with an attack angle of 12 degrees. The air enters the domain with a velocity magnitude of 45m/s and passes over the airfoil.
To capture the flow patterns near the airfoil’s surface and to calculate drag and lift forces precisely, the SST k-omega model is used.
Flap Conclusion
At the end of the solution process, two-dimensional contours related to the velocity, pressure, and turbulent viscosity inside the domain are obtained. The contours related to pressure clearly show how the pressure difference between the pressure and suction sides of the airfoil can contribute to the generation of lift force.
Also, the stagnation point in the leading edge can be observed. Furthermore, the wake region is conspicuously observable in the velocity and turbulent viscosity contour.
In addition, based on the calculated values for lift and drag forces, The lift coefficient of an airfoil with and without the flap is equal to 1.2182 and 1.0530, which shows the effectiveness of the flap in aerodynamic lift force generation.
Moreover, the drag coefficient of the airfoil in the presence of a flap is equal to -0.0273, which is less than airfoil without a flap, where the drag coefficient is equal to -0.0822, which proves that flap presence is effective in drag force reduction that is favorable in aerodynamics applications.

Dr. Alverta Block DVM –
Can the simulation predict the lift and drag forces on the airfoil?
MR CFD Support –
Yes, the simulation provides detailed information about the pressure and velocity distribution around the airfoil, which can be used to calculate the lift and drag forces.
Judd Batz –
I’m truly fascinated by the aerodynamic simulation results! Could you shed light on why the drag coefficient is negative when a flap is deployed on an airfoil?
MR CFD Support –
Thank you for your kind words. The negative value for the drag coefficient seems unusual and could be an error in reporting or interpreting the results. Typically, drag coefficients are positive since drag is a resistive force. The negative sign may refer to the relative decrease in drag compared to the airfoil without a flap, emphasizing the pressure reduction due to the flap’s presence. However, without examining the specifics of the simulation settings, it’s hard to provide a definitive answer.
Tiara Ratke –
How does the simulation model the interaction between the airfoil and the surrounding air?
MR CFD Support –
The simulation uses the Navier-Stokes equations to model the fluid dynamics around the airfoil. The turbulence is captured using the k-epsilon model, which accurately predicts the flow separation and reattachment around the flap.
Alfred Kirlin –
Wonderfully detailed product! Does this simulation also allow for an analysis of how different flap angles affect the lift and drag on the airfoil?
MR CFD Support –
Yes, with the versatile tools available in ANSYS Fluent, users can modify the flap angles to study their effects on lift and drag. Adjusting the angle and analyzing the impact on the airflow can enhance understanding of aerodynamic principles and help in optimizing wing designs for various flying conditions.

I recently utilized the ‘Flap Effect on Trailing Edge of an Airfoil’ simulation product by MR CFD for a project. The detailed solution offered two-dimensional contours that captured important differences with and without the presence of the flap. I was particularly pleased with the enhanced lift coefficient when the flap was deployed, which clearly demonstrated its functionality. Moreover, seeing the drag force decrease with the flap’s inclusion simplified the principles of aerodynamics for practical aviation applications. Notably remarkable was understanding the wake region through the velocity and turbulence visualizations. Exceptional work on creating a powerful learning tool!
