Analysis of Very Fast Transients Using Black Box Macromodels in ATP-EMTP

open access: yesEnergies, 2020
Modelling for very fast transients (VFTs) requires good knowledge of the behaviour of gas insulated substation (GIS) components when subjected to high frequencies. Modelling usually takes the form of circuit-based insulation coordination type studies, in

A Composite Finite Element-Finite Difference Model Applied to Turbulence Modelling [PDF]

open access: yes, 2007
Turbulence has been modeled by a two equation k-?turbulence model to investigate the wind induced circulation patterns in coastal waters. Predictions of the model have been compared by the predictions of two equation k-?turbulence model. Kinetic energy of turbulence is k, dissipation rate of turbulence is ?, and frequency of turbulence is ?.

Finite Element Modelling of Pultruded FRP Beam-to-Column Joints

open access: yesFibers
This research addresses the critical gap in accurately modelling pultruded fibre-reinforced polymer (FRP) beam-to-column joints, where previous studies largely ignored progressive damage mechanisms. A novel finite element framework is developed in ABAQUS,

Accuracy improvement for complex harmonic analysis modelling of a wound field synchronous generator

open access: yesThe Journal of Engineering, 2019
Complex harmonic analysis (CHA) provides a computationally efficient alternative to finite element analysis (FEA) for modelling multi-phase wound field synchronous machines. This paper presents three methods that could improve the accuracy of the CHA: by
