Computational Fluid Dynamics


Using years of applied experience and a proprietary software code, Pratt & Miller uses Computational Fluid Dynamics (CFD) to solve airflow related problems. CFD is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. The CFD modeling and simulation can be used to reduce drag over a vehicle body, optimize engine cooling, predict heating and air conditioning performance inside a vehicle, and develop strategies to manage temperatures in an engine bay.

Capabilities & Technology:

  • Established processes to generate high-quality grids rapidly on complex configurations
  • Proprietary tools to improve overall grid quality and increase local grid refinement
  • Proprietary flow solver software and post-processing tools to simplify the analysis of large 3D datasets
  • Access to one of the largest, privately owned super-computing systems in the U.S. used to conduct large-scale full-3D calculations
  • Test execution including component prototyping, scale and full size wind tunnel testing, and on-road testing

Applications:

  • Drag reduction for fuel economy
  • Down force management for performance
  • Airflow through radiator, coolers, brake ducts
  • Engine bay temperature management
  • Underbody air flow
  • Interior heating and cooling performance
