The expected abolishment of SF₆-gas in medium voltage switchgear has prompted a search for replacements for the switch types that depend on SF₆ to obtain the required capability, reliability, compactness and cost. Ablation of polymers can enhance the arc-quenching capabilities in certain electrical...

Due to the enormous carbon footprint of food retail stores the interest in natural working fluids, such as propane (R290) and CO₂ (R744), has recently intensified in the commercial refrigeration sector. In this theoretical investigation the performance of various technologies employing low-global...

We show, by direct numerical simulations, that heavy inertial particles (characterized by Stokes number St) in inhomogeneously forced statistically stationary isothermal turbulent flows cluster at the minima of mean-square turbulent velocity. Two turbulent transport processes, turbophoresis and...

Significant power sector developments beyond 2020 will require changing our approach towards electricity balancing paradigms and architectures. Presently, new electricity balancing concepts are being developed. Implementation of these in practice will depend on their timeliness, consistency and...

Studies of hydropeaking‐induced stranding mortality on fish populations have been confined to analysis of empirical data and/or short‐term hydraulic‐habitat modelling of individual events and are thus limited as to how they may be used to infer long‐term effects in fish populations. In this study...
