PHOENICS, which is owned and developed by CHAM, is a powerful multi-purpose Computational Fluid Dynamics (CFD) software package.

PHOENICS provides an accurate, reliable, cost-effective, and easy-to-use tool to simulate a range of processes involving fluid flow, heat or mass transfer, chemical reaction and/or combustion in engineering equipment and the environment. With the longest history of validation and a large user base, it is not surprising that PHOENICS has a proven track record in nearly every branch of science and engineering in which fluid flow plays a key role. Many organisations large and small are using PHOENICS to sharpen their competitive edge in the research and development of products and processes involving fluid flow and heat transfer.

PHOENICS offers unrivalled benefits by way of product optimisation at early stages of the design process, facilitating shorter development cycles, cost reductions, and environmental impact assessment for many industries and applications, including:

  • Aerospace
  • Automotive
  • Building services / HVAC / AVA
  • Chemical
  • Combustors & furnaces
  • Electronics cooling
  • Environment
  • Fire/Smoke Hazard / Risk Analysis
  • Heat exchangers and reactors
  • Marine & offshore/petroleum
  • Medical / Health
  • Metallurgical
  • Nuclear and power generation
  • Process
  • Turbomachinery
  • Wind / Water / Solar energy
