Computational Fluid Dynamics (CFD)

Computational modeling is an effective alternative when simulating an industrial process when physical testing is not feasible. Computational fluid dynamics (CFD) software, coupled with actual spray performance data captured in our laboratory, can model various systems to predict process performance.

Detail of BET EAdvanced Spray Engineering Computational Fluid Dynamics.

CFD Simulations Include

  • Fluid flow inside nozzles and piping
  • Evaporation of sprays and cooling of gases
  • Spray trajectories
  • Mixing in tanks

CFD may be used together with physical modeling even when we can't reproduce the actual process in the lab. For example, if spraying a customer's material is impractical or hazardous, it may be possible to combine lab tests of a model using safe process fluids and conditions with a CFD model of the lab setup to validate a CFD model of the actual process.

Often, we will need to run several models to confirm a suitable solution to a problem. For example, a CFD model can predict how much water might evaporate in a gas cooling process given a particular droplet size distribution in the spray. However, it cannot predict the droplet size distribution to achieve a specific amount of evaporation. Each model provides additional insight into the problem and guidance towards an ideal solution.

Finite Element Analysis (FEA)

BETE also uses ANSYS® software for FEA. Some applications of FEA include:

  • Analysis of stresses in solid parts, especially for complex geometry or loading conditions for which analytical solutions do not exist
  • Qualifying fabrications to ASME Boiler and Pressure Vessel Code Section VIII Division 2, part 5
  • Computation of temperature distribution in solids and can be used together with CFD
  • Calculation of mode shapes for vibration analysis and determination of eigenvalues to support buckling analyses
