Most studies on local scouring at grade control structures have principally focused the analysis of primary flow field, predicting equilibrium scour depth. Despite numerous processes, secondary currents were not often considered. Based comprehensive measurements velocities in clear water scours downstream a structure channel with non-cohesive sediments, this study, we attempted to investigate g...

Abstract. This paper presents a model to incorporate the secondary effects of wake steering in large arrays turbines. Previous models have focused on aerodynamic interaction between two The proposed this builds these include yaw-induced recovery and seen turbines when is performed. Turbines operating yaw-misaligned conditions generate counter-rotating vortices that entrain momentum contribute d...

The transition to a renewable energy system challenges power grid operation and stability. Secondary control is key in restoring the its reference following disturbance. Underestimating necessary capacity may require emergency measures, such that solid understanding of predictability driving factors needed. Here, we establish an explainable machine learning model for analysis secondary Germany....
