Aerodynamics

Strict fuel economy and emissions regulations are placing increased importance on efficient aerodynamic design. Getting the design right as early in the process as possible will not only affect overall packaging, but the brand image too. To bring more efficiency into the development process of external aerodynamic parts, the use of CFD as a tool in the evaluation and understanding of aerodynamic performance becomes more and more important.

Siemens PLM Software offers best-in-class 3D CFD capability to help you understand the aerodynamic impact of design changes as you pursue increasingly tough performance targets.

By optimizing the aerodynamic performance of your vehicle from early in the design process, you can minimize the amount of fuel required to overcome aerodynamic resistance, and also reduce the impact of its acoustic signature on passengers and pedestrians. The use of best in class CFD tools will allow more design iteration upfront, so that the aerodynamic performance is at an advanced stage of refinement before progressing to wind tunnel validation.

Our Siemens PLM Software solutions have automatic shape optimization capabilities that guide you through making intelligent design decisions when deciding between trade-offs such as internal cooling requirements and external drag and the multi-physics capability allows water management and soiling analysis from within the same software.

Možnosti řešení

Explore the key areas of this solution.

Aero-acoustics

Flow induced noise is a significant component of the acoustic signature of a vehicle (or other product). Simcenter  offers an extensive library of accurate models for predicting aeroacoustics noise sources, including: steady state models, direct models (DES/LES), propagation models and acoustic perturbation equations (APE) solver. 

Simcenter supports hybrid aero-acoustic methods in which at first, a CFD simulation is used for capturing flow turbulences, which are translated into aero-acoustic sources to be plugged into a second acoustic (FEM) simulation model. The latter then predicts the acoustic propagation of these sources, including reflections and absorption in the environment. As such, for instance the cooling noise of electronic equipment of the HVAC noise in a car can be predicted.
