Computational fluid dynamocs (CFD) is a sophisticated computer-based design and analysis technique used to simulate fluid flows and processes. By utilizing CFD, Flygt is able to offer a high level of accuracy in predicting flow, and in some cases mass transfer, in a variety of situations. Flygt engineers can model complete pumps with rotating impellers or more complex systems such as pump stations, mixing or aeration tanks. In most cases, time averaged conditions are considered, but time-dependent simulations are also possible if the flow is unsteady.
To help evaluate and develop pumping solutions, Flygt engineers use different flow visualization and data-reduction techniques to translate vast quantities of data generated in the simulation process into an intelligible form. We typically study everything from the overall flow patterns in a pump station to minute details of the flow conditions inside the pump inlet. We look for the risk of any adverse hydraulic conditions and develop efficient and reliable solutions.
We insist on using the best CFD software that is commercially available. In fact, Flygt engineers use the same software as that being used by other major high-tech industries: aerospace, automotive, power, chemical and environmental. We also take great care to ensure that the numerical simulations are consistent with the measurable, physical reality typical of our applications. Since we only work with contaminated water, it gives us a unique expertise in the field since we are experts on the analysed media. Laboratory and full scale validation have proven the computational tools to be highly reliable.
