A High Current Switching test bench to estimate switching losses for power switches

2018-08-09T17:43:58+00:00July 27th, 2018|Power Electronics & Converters|

Our High Current Switching test bench is now operational! This one is integrated to the Power switches characterization platform, which can be used to fully characterize power switches.

Uncertainty Quantification for the Eulerian-Lagrangian simulation of evaporating sprays

Evaporating sprays can be almost routinely simulated using an Eulerian-Lagrangian approach which relies on a RANS modeling of the continuous phase and a Lagrangian description of the discrete phase, including a turbulent dispersion model to express the effect of turbulent fluctuations within the carrier phase on the spray particles and an evaporation model for the spray droplets.

With a new semi-automatic injection mixer and an injection molding press, the material characterization and the processing of our samples will take less time – close to industrial production thanks to the Automatic Pressure Gelation (APG) method.

High Voltage Electrical Properties of Epoxy / h-BN Microcomposites
