Description
Description
A rear spoiler is a device commonly used on vehicles to improve their aerodynamic performance. The main purpose of this study is to investigate the effect of changing the spoiler angle on the aerodynamic performance of a hatchback car.
The inlet boundary condition is a uniform flow with U = 40 m/s and a turbulence intensity of 0.2%. The corresponding Reynolds number (Re) based on the model’s height is 768,000.
In the case of the outlet boundary, the outlet pressure is applied at zero gauge pressure. The side and top walls of the domain are defined as symmetry boundary conditions. The ground and model surfaces are set as no-slip walls.
The computational domain looks like a rectangular box. Since the model is symmetric and the flow is steady, all simulations are performed for half of the flow domain with a plane of symmetry at the centerline location. The cross-sectional area of the half-flow domain is 1738 mm × 1129.5 mm (height × width).
This study uses the RANS-based Computational Fluid Dynamics (CFD) method. To validate the project, obtained numerical results are compared with the data of the ‘Effect of spoiler angle on the aerodynamic performance of hatchback model’ paper.
The model is designed in the Design Modeler software, and then the meshing is done by ANSYS Meshing software. That is in a fully Polyhedra grid type that results in a 935,500 element number.
Methodology: Spoiler Angle Aerodynamic Effect
The turbulence model is the k-epsilon model with an improved wall, which is one of the useful two-equation models. Also, a fixed pressure-based solver is used to achieve steady state simulations.
Conclusion
The numerical results show that in the positive spoiler angle, the aerodynamic lift of the hatchback model is significantly reduced. However, when configured at a negative pitch angle, the Effect of the spoiler on lift reduction is inadequate. Although aerodynamic lift decreases by increasing spoiler angle, it was accompanied by a decrease in drag.
Finally, as seen in the charts above, the pressure coefficient parameter has acceptable accuracy compared to Fig-7 in the paper. Fig-7 is shown below:

Doyle Beier MD –
The explanation is very detailed and structured. But could you clarify if the positive spoiler angle also leads to an increased amount of drag alongside the reduction in lift?
MR CFD Support –
In our simulations dealing with the effect of the spoiler angle on aerodynamics performance, a positive spoiler angle does reduce lift. However, the relation with drag is dependent on multiple complex factors. The analysis showed that when the spoiler angle is positive, there can be scenarios where drag increases due to the air deflection caused by the spoiler, but there are also setups and specific angles where the impact on the drag can be minimized or possibly even reduced due to improvements in the car’s overall aerodynamic shape induced by the spoiler configuration.
Eden Rogahn –
I’ve been studying how the spoiler angle affects car performance and was impressed with the CFD analysis provided. The results demonstrating lift reduction with positive spoiler angles were particularly insightful. The numerical validation seems thorough, aligning with research findings. To improve understanding, would it be possible to get insight into the forces acting on the model due to changes in the spoiler angle? Understanding the forces would help explain performance changes on the vehicle.
MR CFD Support –
In each simulation at different spoiler angles, forces such as lift and drag are computed. With a positive spoiler angle, the downforce on the vehicle increases, reducing lift. This gives better stability at high speeds. Conversely, a negative angle does not contribute significantly to lift reduction. The study balances these aerodynamic forces to achieve desired performance outputs.
