This project involves the Computational Fluid Dynamics (CFD) analysis of a custom-designed aircraft geometry created in SolidWorks, imported into ANSYS Fluent via STL format. The goal was to study aerodynamic behavior including pressure distribution, lift, and drag forces under turbulent flow conditions.
β Tools Used: SolidWorks | ANSYS Fluent | CFD Post | Meshing Tools
β Skills Involved: CAD Design, Meshing, Boundary Condition Setup, Flow Simulation, Turbulent Modeling
- Designed a simplified fixed-wing aircraft model using SolidWorks surface and solid modeling tools.
- Exported the final geometry as
.STLfor compatibility with Fluent preprocessing.
- Imported the STL model into ANSYS Fluent Mesher.
- Generated unstructured tetrahedral mesh, with inflation layers near the surface to capture boundary layer effects.
- Mesh quality was refined based on skewness and orthogonality metrics.
- Flow Type: Steady, Incompressible Turbulent Flow (k-Ξ΅ Model)
- Boundary Conditions:
- Inlet: Velocity Inlet
- Outlet: Pressure Outlet
- Aircraft Body: No-slip wall
- Air properties were set to standard sea-level conditions.
- Visualized velocity streamlines, pressure contours, and wall shear stress on aircraft surfaces.
- Calculated lift and drag coefficients, and observed flow separation zones on the tail and wing edges.
- Understood aerodynamic behavior of custom aircraft geometry under ideal flow conditions.
- Demonstrated proficiency in CAD-to-CFD workflows, meshing practices, and turbulence modeling.
- Strengthened knowledge of fluid behavior around aero surfaces with curvature and fuselage taper.
