Computational Fluid Dynamics at ISE

ISE are experts in the field of computational fluid dynamics (CFD) and wave propagation analysis. We utilize, and have developed numerous predictive computer codes to help our clients understand the effects and impacts from subsonic, transonic, and supersonic flows associated with acoustic wave propagation, aerodynamic flow, rotor and fan wash, vortex shedding, and high pressure sources.

Our CFD capabilities include, but are not limited to the following:

  • Predictive modeling strategies.
  • Advanced acoustical propagation analysis.
  • Fluid-structure interaction studies including added-mass effects.
  • Dynamic vortex flutter and instability analysis.
  • Predictive model development for client-specific needs.
  • Web interactive CFD acoustical models for clients.

Featured Video Clip (Concrete Fail)

ISE performing load testing of concrete test specimens to determine its axial compressive failure characteristics.

In this example, you can see quite dramatically how concrete fails under a compressive load. Once the ultimate stress is reached, the load carrying capacity of the material rapidly drops off producing the fracturing seen in the video.
