Numerical Modelling and Optimisation at TWI
The Numerical Modelling and Optimisation Section at TWI supports industry with a range of computational engineering capabilities from finite element analysis (FEA) and computational fluid dynamics (CFD) to data analysis and software development. TWI provides a range of bespoke electromagnetics simulation services to its Industry Members: some examples are given below.
Defect identification in circuitry
By analysing the temperature profile of current-carrying wires heated by Joule heating (the process by which the passage of electric current through a conductor produces heat), defects in circuitry can be identified. Algorithms, such as machine-learning, can then be incorporated into quality assurance procedures as part of circuit board manufacture to identify defects from the thermal profile of a circuit board.
Electromagnetic models have been utilised to quantify the risk of using non-conductive pipes for gaseous hydrocarbon transport by simulating the electrostatic charge accumulation on non-conductive pipes due to water droplet and sand particle impact for Saudi Aramco. Quantification of the risk ensures that the level of charge does not build to such a level as to break-down the pipe wall, causing pin-holes to evolve (Figure 2). This work was presented at the NAFEMS World Congress and will be published in the upcoming edition of “Oil and Gas Pipelines” by Winston Revie.
