Computational Fluid Dynamics
Vehicle Aerodynamics
CFD
Computer simulations of fluid flow
Very complex mathematical models
Very compute intensive, usually requiring super-computer with parallel architectures
Does not replace physical studies in wind tunnels (yet)
CFD Simulation
Examples of CFD simulation
- Streamlines
- Pressures
- Viscosity
- Velocities
- Flow and flow separations
- Boundary layers
- Surface friction
- Load analysis (lift, drag, and side forces)
- Example
- Pressure distribution and streamlines on a Porsche 965
- Example
- Viscous-flow simulation of the separated flow over a two dimensional
model of the Mazda RX-7
- Benefits
- Lower analysis costs
- Rapid availability of test data
- Design improvements via CAD models only
- Elimination of physical models
