 Computational Fluid Dynamics (CFD)
|
|
|
Computational Fluid Dynamics (CFD) is a computer modeling technique for simulating fluid flow. CFD can predict air speed and direction, temperature, humidity, pressure, turbulence levels and concentrations of contaminants at thousands of points in a space to be modeled to help design laboratories, clean rooms, schools, theaters, hospitals, sports complexes and industrial facilities. Designers can easily interpret the predicted flow patterns shown on color images or animations. Air Quality and ventilation problems are readily identified and solutions quickly tested.
CFD is useful for building, environmental and industrial projects when:
- Distributions of gas or liquid flow velocity, pressure, temperature, turbulence and contaminant concentrations are important
- Demanding design criteria must be met
- It is not possible to measure or observe existing flows because the process would either change the flow or the flow regime is too hazardous for measurement or monitoring equipment or personnel
- Traditional engineering calculations are subject to unacceptable levels of uncertainty
Typical projects:
Building services:
- Thermal comfort in window areas
- Natural and hybrid ventilation efficiency
- Atrium smoke management
- Air flows induced by moving vehicles (e.g., stations and tunnels)
- Baseball trajectories
- Pedestrian wind environment
- Patient isolation rooms
- Rain Infiltration
- Contaminant migration in a building
- Risk of drafts in sensitive interior spaces
Industrial services:
- Spray cooling towers
- Automotive paint spray booths
- Stack and duct pressure losses
- Dropout boxes
- Wet scrubbers
- Pollutant containment in fume hoods
- Recovery boiler analysis
- Air distribution for fiber manufacturing processes
