Computational Analysis

Computational Fluid Dynamics (CFD)

When duplicating an industrial process for physical testing is not feasible, computational modeling is an effective alternative. Computational fluid dynamics (CFD) software, coupled with actual spray performance data captured in our laboratory, can model a wide variety of systems to predict distribution, velocity, temperature, flow paths, droplet evaporation, wall hit, and almost any physical quantity. CFD lets you know that your process is going to work before you build it.

Three ways to investigate fluid phenomena:
  • Analysis
    • Bernoulli’s equation
    • Diffusion law
  • Experimentation (lab work)
  • Computation
    • Use basic fluid equations all solved simultaneously

What Kinds of Problems Can We Solve with CFD?

  • Fluid flow inside nozzles and piping, even in complex geometries
  • Evaporation of sprays and cooling of gases
  • Droplet breakup at nozzle orifice 

Finite Element Analysis (FEA)

  • Used for analysis of stresses in parts
  • Methods are similar to CFD, breaking up the part into tiny elements and calculating movement and stress on each element
  • Used for qualifying ASME code compliance
