Modelling and Simulation

Computer modelling and simulation are powerful techniques used to predict the three dimensional behaviour of fluids and process components. TUV NEL’s expertise lies in combining practical test and field experience with modelling results to produce practical solutions to challenging problems.

There are two principal modelling and simulation techniques which we utilise:

Computational Fluid Dynamics (CFD)
CFD studies the flow of liquids, gases, particulates, and mixtures of all three, through engineering components and the environment.

CFD is used to improve and optimise products and processes. It can be particularly effective in product design, failure investigation and detailed flow behaviour studies involving complex and inaccessible flows. In addition, CFD can provide performance data which can help confirm technology selection prior to equipment purchase.

CFD has a number of practical advantages over physical testing especially when high pressure, hot, cold or toxic fluids are involved or where precise control is required.

Other Modelling
We also use a range of other modelling and simulation techniques. These include:-

HTFS (Heat Transfer Fluid Flow Service) and PPDS (Physical Property Data Service) software to investigate the thermal and physical properties of processes and components.
Atmospheric Dispersion Modelling to examine the impact of the external environment on the flow of emissions.
