Aerodynamics is a key vehicle functionality to achieve the industry goals regarding emissions and vehicle efficiency. Aerodynamics rivals weight as energy consumer at low speed cycles (WLTP) and is the main energy consumer at highway cycles, thus the Cd targets are lowered year by year. To achieve best in class aerodynamic values (Cd & Cl), IDIADA provides deep knowledge of the contribution of all vehicle parts to the aerodynamic forces and an experienced CFD and wind tunnel testing team.
The IDIADA CFD team has more than 25 years of experience in simulating various automotive fluid dynamics problems: aerodynamics, thermal & cooling, multi-phase, aero-acoustics, etc. We have in-house hardware premises and in order to be aligned with our customers, we are skilled in the most used software packages: STAR-CCM+, ANSYS, OpenFOAM, PowerFLOW, etc.
Aerodynamics testing in real driving conditions include steady and transient events.

IDIADA provides turn-key wind tunnel testing support in many different commercial wind-tunnels worldwide. The IDIADA support includes: mock-up definition and construction, test scheduling and on-site support at the testing sessions.
50% mock-up testing is a very attractive option at the initial stages of a project. IDIADA utilizes a former F1 wind tunnel facility to provide quick aerodynamic assessment at the concept phase. IDIADA designs and manufactures 50% mock-ups with sting fixation and single belt wheel rotation systems. Wind tunnel specifications:
In order to provide optimal solutions for airflow modelling, IDIADA develops proprietary software based on Vortex methods and Artificial Intelligence. Two differentiate strategies for high fidelity turbulence modelling are developed by IDIADA:
