Modelling microdischarges in metal vapour of cadmium in comparison with electrical measurements - Dataset

The dataset provides the data related to the modelling of microdischarges in metal vapour of cadmium. Such microdischarges occur in a testing equipment for the safety assessment of electric devices for explosion protection. A one-dimensional unified non-equilibrium model that resolves the entire discharge gap is employed and simulations are conducted for a constant current of 60mA with gap lengths varying between 20 μm and 160 μm. These conditions match the experiment and enable a comparison with measured data. The predicted discharge voltage obtained as a function of the discharge length is compared to the measurements and shows a good agreement. The model provides the heat generation relevant to the prediction of a gas mixture ignition.
