Calculation and Analysis of the Thermophysical Properties of Air-Aerosols Mixtures
Yaguibou Wepari Charles1, * , Pafadnam Ibrahim2 , Banouga Adjigkiga3 , Yann Cressault4 , Kagone Abdoul Karim3 , Kohio Niessan5 , Koalaga Zacharie
Electrical equipment, such as circuit breakers, often encounters operational issues, such as short-circuit failures. These malfunctions can be attributed to the deposition of aerosols containing aluminium oxide (Al2O3), calcium oxide (CaO), ferric oxide (Fe2O3), and silica (SiO2) on the devices. Previous studies have examined the influence of(...)
