A numerical two-dimensional modelling of eddy-currents: An application to non-destructive test

Numerical Investigation of the Structure of Density Currents in a two Dimensional Channel

Numerical Modelling of Two-dimensional and Axisymmetric Gravity Currents

A series of two-dimensional, axisymmetric and three-dimensional numerical flow simulations using an Implicit Large Eddy Simulation (ILES) are carried out for gravity-driven fluid flows, the results are compared directly with experiments undertaken to test the model. Two-dimensional results show that the Large Eddy algorithm is successful in modelling a gravity current’s large scale structure. E...

Heterodyning based portable instrument for eddy currents non-destructive testing

The development and implementation of a portable eddy currents testing instrument with heterodyning based measurements is presented in this paper. The instrument is composed by a dedicated electronic measurement circuitry embedded inside a rugged tablet computer for control and visualization and that interfaces a small footprint planar eddy currents probe. A DDS waveform generator and a transco...

Eddy Current Non-Destructive Testing Application Research of Marine Engines

Exist forms and criticalities of disfigurements of marine engines were studied from main propulsive engine, auxiliary facility and hull. Eddy current Non-destructive testing method was brought forward to disfigurement inspection of marine engines with advantages such as celerity and nicety. Cracks, as one form of disfigurements, testing of marine engines were demonstrated in detail, and the dev...
