Aerodynamics simulation (CFD)
Customer: Various customers
Project tasks
During the development process or during modernisation, aerodynamic influences such as crosswind or vehicle air conditioning of a vehicle must be assessed. Often the final verification requires investigations in a wind tunnel or climatic wind tunnel. However, CFD (Computational fluid dynamics) simulations are ideal for an initial assessment and optimization, as they generally provide reliable results at significantly lower cost.
Analyses:
- Crosswind stability (aero-dynamic coefficients and wind characteristics curves) according to EN 14067-6
- Climatic studies and thermal comfort
Our Approach
Crosswind assessment according to EN 14067-6
The EN 14067-6 provides for the evaluation of crosswind with aerodynamic coefficients, which can be obtained either by wind tunnel tests or by CFD simulations. PROSE can determine these coefficients by CFD simulations and derive characteristic wind curves. The influence of the vehicle design on the crosswind stability can be considered in the design phase. In the case of changes to the vehicle exterior shape during conversions, the influence can be assessed and in the case of minor changes, proof of crosswind stability can also be provided.
Investigation of vehicle air conditioning
CFD simulations allow first estimations for climatic-technical investigations according to European standards, which are based on tests in the climatic wind tunnel. An optimization with CFD simulations within the scope of the design of the air conditioning system generates additional safety and can avoid costly adjustments and repetitions of measurements in the climatic wind tunnel.
Customer benefit
PROSE can support you during the development process or during a modernization with CFD simulations to reduce costs and risks of wind tunnel and climatic wind tunnel tests.
