External Aerodynamics
CFD has been long used in the automotive industry to predict aerodynamic characteristics of vehicle shapes and sizes. CFD simulations provide critical design information such as lift, drag, and thermal loads. The CFD2000 package includes advanced capabilities for aerodynamic analysis of automotive bodies in turbulent flows.
CFD2000 was used to optimize the shape of a truck air-dam. Pressure and viscous forces were determined for various design shapes to determine instability characteristics of specified shape designs. Other Example Aerodynamic Applications
Engine Combustion Processes Example Application: CFD2000 was used to model the flow and combustion inside an engine cylinder. The fuel (methane) and oxygen enter the cylinder chamber through separate outlet ports. During the intake stage, the piston head moves down and combustion occurs. The residual gases are ejected from the cylinder chamber through the outlet port during the upstroke of the piston head.

Automotive Electronic Applications
As the automotive industry tends to put more components into a smaller space, thermal management has become one of the key factors in designing the new generation of computers and many other electronic devices. CFD simulations can help optimize cooling system design, thereby increasing components lifetimes and minimizing the possibility of hardware errors.
CFD2000 has been used for 3D simulation of air flow and heat transfer of electronic systems including: heat sinks, individual components, multi-chip modules, and computer boards

The system includes modules for geometry creation and mesh generation, a Navier-Stokes equation solver, and advanced scientific visualization.
Computational Fluid Dynamics (CFD) What Is CFD?
Computational Fluid Dynamics is a powerful engineering tool for simulating all types of fluid flows. CFD simulations produce detailed descriptions of flow characteristics including values for velocities, pressures, and other variables. Thermal characteristics and other advanced physics, like chemical reactions, particle flow, free-surface flow, can also be simulated. Why use CFD?
Computational Fluid Dynamics can significantly reduce design and development time, provide detailed information otherwise not available from physical experiments, and quickly simulate a wide range of flow conditions. The results are improved designs, lower risk, and shorter time to market for a product or process. How does CFD work?
CFD simulations involve solving numerically the fundamental laws of physics, called governing equations, which mathematically describe the properties and motion of fluids. The CFD modeling process occurs in three fundamental steps.
