Enhancing Vehicle Performance: A Deep Dive into our External Aerodynamics Study of Roof Cover

Automotive manufacturers continually face the challenge of enhancing vehicle performance and aesthetics while maintaining functionality. A fundamental challenge is the accumulation of dirt and bug on camera glass, especially in today's vehicles where cameras are significant for safety and navigation. Poor aerodynamic design can make this issue intense, leading to degraded performance and customer dissatisfaction. The need for precise aerodynamic analysis has never been greater, especially for vehicle roof designs.

The Scope of Aerodynamics Study

We aimed to predict the impact of dirt and bugs on the camera glass of car roof covers by identifying areas of low pressure and high vortex zones. This analysis focused on several critical aspects:

• Understanding Flow Dynamics: We determined how airflow interacts with the vehicle's roof cover containing camera glass at varying speeds.
• Predicting Dirt Accumulation: Accurately identifying how and where debris collects on the camera glass was imperative for design refinements.
• Ensuring Camera Functionality: Protecting the optical performance of camera systems was a cornerstone of our study.

With these goals in mind, we undertook an extensive study of external aerodynamics using computational fluid dynamics (CFD) modeling.

Improving Performance: Our CFD-Driven Solutions

To accurately study the aerodynamic performance of the roof cover, we conducted a series of CFD analyses:

Creation of a CFD Model:

We created a comprehensive external aerodynamic CFD representation of the car, incorporating the roof cover in detail. This was the cornerstone of our analysis, allowing for a realistic modeling of the airflow distribution.

1. Multi-speed Analysis: We have analysed the design for multiple car speeds from 30 mph to 100 mph. This resulted in consideration of the effect of different velocities on air movement and debris deposition on the camera glass due to the roof design.
2. Flow Separation Studies: We analysed boundary layer separation zones near the roof cover, which is significant for predicting areas of high vortex generation, along with low pressure that may lead to dirt accumulation.
3. Visualization of Flow Patterns: Our findings were analyzed to reveal the flow of air over the car roof and into the wake region, providing a better understanding of the debris impact on the camera glass position, relative to the roof cover design.

Demonstrating Results: Crisp Benefits through Data-Driven Intelligence

Our detailed analysis provided clear insights into airflow and its significance in vehicle design.

Refined Airflow Characterization:

Our study clarified the flow behaviour at various vehicle speeds, enabling design teams to make more informed, speed-specific decisions throughout the vehicle's development cycle.

Precise Dirt and Insect Impact Forecast:

We identified areas of low pressure and strong vortices with enough precision to forecast where contaminants are likely to settle on camera lenses. Additionally, we found that the accumulation of dust on the front of the camera glass can be managed by making suitable changes to the aero features in the roof cover, based on flow dynamics, which work across the entire range of vehicle operational speeds. This ensures that the safety is not compromised due to roof cover styling.

Proactive Design Guidance:

With these insights, automotive engineers can look ahead and make design changes that improve both the aerodynamic efficiency and visual appeal of vehicles. These improvements can be implemented while keeping essential systems, such as imaging and sensing, fully operational.
