COMPUTATIONAL MODELING AND SIMULATED SPRAY ANALYSIS
Computational Fluid Dynamics (CFD)
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
