Computational fluid dynamics (CFD) is an engineering tool that uses numerical methods to analyze physical phenomena involving fluid flow. Multiphase flows, in particular, present many challenges due to intricate mixing and interfacial transients that can occur. Southwest Research Institute (SwRI) engineers have more than 30 years of experience in using and customizing both commercial and SwRI-developed CFD codes to meet our clients' needs.

SwRI conducts research for a diverse range of clientele problems in the oil and gas industry, space science, medical community, food processing, environmental agencies, and nuclear regulatory commission. Reasons for employing CFD alone, or in conjunction with experimental testing, may include the need for:

  • Rapid analysis with reduced resource requirements
  • Fewer prototype iterations
  • Corroboration of experimental results
  • Investigation of parameters not obtainable via traditional experimental techniques (due to time scales, impracticality of sensor placement, visual obstructions, etc.)


At SwRI, we have applied CFD techniques to model a wide variety of industrial scenarios, including:

  • Environmental flows
  • Oil and gas production/transport
  • Pipeline accidental spill and leak assessment
  • Space vehicle propellant dynamics
  • Combustion
  • Medical device operation
  • Food processing
  • Fluid-structure interactions

Using state-of-the-art software in combination with parallel processing capabilities, SwRI strives to provide timely solutions to our clients' development and operational challenges. Large or small, we welcome your inquires. Please let us know if there is a problem with which we can assist you.
