The Design – Volume Rendering on Rear Spoiler “Molto Veloce” Lamborghini Aventador | Ansys CFX
This simulation is about an Analysis of Volume Rendering on Rear Spoiler “Molto Veloce” Lamborghini Aventador using ANSYS CFX software. We perform this CFD project and investigate it by CFD analysis.
- Aerofoil shape: Like the wings on a race car, the Molto Veloce’s aerofoil shape is designed to create negative lift, or downforce, at high speeds. This pushes the car down onto the track, increasing traction for better high-speed cornering and stability.
- Venturi effect: The spoiler’s venturi setup is designed to manage and accelerate airflow over the car’s body. When combined with the Molto Veloce rear diffuser, it contributes to the “ground effect,” increasing downforce at the rear axle by creating a low-pressure zone underneath the car.
- Agressive aesthetic: The large, fixed wing visually transforms the car’s silhouette, giving it a more powerful, track-oriented presence. DMC created the Molto Veloce kit to address the “tame” look of the factory Aventador’s rear end.
- Construction: The wing is made from lightweight and strong carbon fiber, produced using a vacuum infusion process for a high-quality finish.
- Wind tunnel and CFD testing: DMC states that its engineers use wind-tunnel software and Computational Fluid Dynamics (CFD) to optimize the wing for maximum aerodynamic efficiency.
- Wing + Base Spoiler: A complete replacement of the OEM Aventador’s active spoiler and mounting base with a fixed DMC carbon fiber unit.
- Top Wing only: An “add-on” version that allows the OEM base to be retained and the DMC top wing element to be mounted to it. The installation process for this variant requires removing the factory rear bumper.
| Feature |
DMC “Molto Veloce” wing
|
OEM Lamborghini Aventador spoiler
|
|---|---|---|
| Functionality | Fixed-position wing designed for maximum downforce. | Active, electronically adjustable spoiler that changes angle based on driving conditions. |
| Design | Large, fixed-position wing providing a more aggressive, track-inspired aesthetic. | More subtle, integrated spoiler that blends with the car’s body. |
| Aerodynamics | Creates significant, constant downforce at the rear axle, improving traction and cornering stability. | Optimizes aerodynamics for different speeds, reducing drag on straightaways and increasing downforce in corners. |
| Materials | Lightweight carbon fiber, often with a choice of gloss or matte finish. | Material depends on the specific Aventador model, but is generally less prominent. |
This analysis has tried to simulate and analyze of Volume Rendering on Rear Spoiler “Molto Veloce” Lamborghini Aventador using ANSYS CFX software.
Geometry & Grid
The geometry required for this analysis was generated by Ansys Design Modeler software. The meshing required for this analysis was also generated by Ansys Meshing software. The mesh type used in this analysis is unstructured. The total number of volume properties for geometry is 4,3649e+009 mm³.
Model
In this analysis, a steady-state analysis type was used to obtain the results to check the fluid flow. In this analysis, non-buoyant models have been used, and stationary domain motion has also been activated in this analysis.
Boundary Condition
The flow input for this geometry of a Rear Spoiler “Molto Veloce” Lamborghini Aventador directs the flow of air at a fluid temperature of 25°C into the geometry. The turbulence boundary condition of a Rear Spoiler “Molto Veloce” Lamborghini Aventador wall is considered to be shear stress transport according to the working conditions. The wall function is defined as automatic in the name selection section of the turbulence boundary condition. The normal speed for the mass momentum is equal to 30 m/s. The turbulence for the design modeler is set with an intensity equal to 5 %.
Discretization of Equations
In this analysis, high-resolution is used for the advection scheme of the basic settings. In this analysis, the first-order is used for turbulence numerics. In this analysis, the residual type of convergence criteria is RMS and the residual target of convergence criteria is 0,00001 with conservation target is equal 0,0001.
The results are presented as pressure contours as well as volume rendering.
