International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.High‐current interruptions aggravate arc contact ablation, and arcing time strongly influences the gas‐blast capability of self‐energy SF6 circuit breakers. This study quantifies the effect of arcing time on gas flow characteristics while accounting for cumulative arc contact ablation over repeated operations.

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.This study is aimed at addressing combustion instability phenomena observed during the operation of dual‐burn‐rate Solid Rocket Motors (SRM) with a large aspect ratio. Previously, the acoustic mode of the combustion chamber (induced by external excitation) and the vortex shedding frequency were typically analyzed independently, and the probability of ...

NUMERICAL INVESTIGATION OF CHOCKED CONVERGING-DIVERGING NOZZLES FOR THRUSTER APPLICATION
International Islamic University Malaysia Engineering Journal, 2011 The need for low-thrust propulsion systems for small scale spacecraft is growing. Low thrust characteristics generally lead to low Reynolds number flows from propulsive devices that utilize converging-diverging nozzle.
