Hey everyone! 👋
I’ve been experimenting with SOLIDWORKS Flow Simulation and wanted to share an exciting project I just completed. I simulated the airflow around an airfoil (wing profile) while the flap lowered.

This is a split type flaps which are special parts on a wing that extend to change its shape, helping the wing create more lift. By increasing the curve (or camber) of the wing, flaps make the air bend more as it flows over the surface, which boosts lift even when the aircraft is moving slowly. This is especially useful during low-speed flight, as flaps allow the plane to stay in the air with less speed. However, flaps also increase drag, which helps slow the plane down and gives pilots better control during critical moments, such as when approaching a landing or flying at low altitudes. |
This image shows how adding a flap to the airfoil changes the airflow and increases lift. I used CFD (Computational Fluid Dynamics) to see what happens when the flap is lowered.
You can clearly see how the airflow bends more downward, and the pressure changes on the top and bottom of the wing. This difference in pressure helps the wing create more lift — which is really important during takeoff and landing.
🛠️ What makes SOLIDWORKS Flow Simulation so powerful?
- Seamless integration with your 3D model — no need to switch software
- Visualizes airflow, pressure, temperature, and velocity with clear plots
- Simulates real-world physics like turbulence, heat transfer, and rotation
- Easy to test design changes with built-in parametric and what-if studies
- Saves time and cost by reducing the need for physical prototypes
Here I calculated the coefficient of drag, with this formula:
(Inlet velocity = 80 km/hr)

💬 Feel free to drop your thoughts or ask me anything about the simulation setup or boundary conditions. I would love to geek out with fellow aero enthusiasts!
