Investigation on flow field characteristics in an open-pit coal mine [PDF]
Environmental Science and Pollution Research, 2021 Abstract In this paper, the atmospheric flow field characteristics in a deep open-pit mine are investigated numerically and theoretically. A theoretical model on the recirculation length based on the energy equation is used, a total variation diminishing (TVD) difference scheme with second order accuracy is used to solve the NS equations with a

Discharge characteristics in inhomogeneous fields under air flow
Proceedings of the Nordic Insulation Symposium, 2017 This research investigates the impact of high velocity air flow on Partial Discharge (PD) patterns generated in strongly inhomogeneous fields. In the laboratory, a needle plane electrode configuration was exposed to a high electrical DC-field and a laminar air flow up to 22 m/s. The needle was connected to a variable DC potential of up to 100 kV over a
