Industry

Automobile, Electric Vehicles

Challenge

The client designed an ultra-efficient electric vehicle for its target market. The design plan was to use an aerodynamic exterior profile for minimal drag and lightweight composites for the structures.

 

An engineering analysis of the design was required to verify design goals. Timetooth with its expertise in CFD simulations partnered to assess aerodynamic performance of the vehicle under various operating conditions.

Service Area

Advanced Engineering Simulations

Timeline

April 2021 to September 2021

For calculating the fuel efficiency of the initial design of the car, Timetooth leveraged advanced CFD analysis to predict pressure contours, velocity contours and wake formations.

Engineering Design Analysis

1. OpenFoam solver was customized with established international benchmarks.

2. The vehicle aerodynamic model was meshed and solved with required boundary conditions.

3. Simulation results were interpreted for minimizing drag.

4. The effect of various parameters like the change of curvature, splitters, etc. on the performance of the vehicle were analysed.

Solutions

For calculating the fuel efficiency of the initial design of the car, Timetooth leveraged advanced CFD analysis to predict pressure contours, velocity contours and wake formations. 

OpenFoam solver was customized with established international benchmarks. The vehicle aerodynamic model was meshed and solved with the required boundary conditions as per the operating scenario specified. 

Simulation results were then interpreted for minimizing drag. Additionally the effect of various parameters like the change of curvature, splitters, etc. on the performance of the vehicle were analysed. Cumulative assessment of simulation results was done and specific design directions were shared with the client. Design was finalised incorporating the suggestions.
