The 2030 Agenda of the United Nations (UN) revolves around Sustainable Development Goals (SDGs). A critical step towards that objective is identifying whether scientific production aligns with SDGs' achievement. To assess this, funders and research managers need to manually estimate impact their funding agenda on SDGs, focusing accuracy, scalability, objectiveness. With this in mind, work, we develop ASDG, an easy-to-use Artificial-Intelligence-based model for automatically potential papers...
For adverse-pressure-gradient turbulent boundary layers, the study of integral skin-friction contributions still poses significant challenges. Beyond questions related to integration boundaries and derivation procedure, which have been thoroughly investigated in literature, an important issue is how different terms should be aggregated. The nature these flows, exhibit in-homogeneity streamwise direction, usually results cancellation between several with high absolute values. We propose a...

Abstract Thermal anemometry sensors for time-resolved velocity measurements average the measured signal over length of their sensor, thereby attenuating fluctuations stemming from scales smaller than wire length. Several compensation methods have emerged wall turbulence, most prominent ones relying on small-scale universality in canonical flows or reconstruction based two attenuated variance profiles obtained with different To extend these to non-canonical flows, present work considers...
Wake analysis plays a significant role in wind-farm planning through the evaluation of losses and energy yield. Wind-tunnel tests for wake studies have high costs are time-consuming. Therefore, computational fluid dynamics (CFD) emerges as an efficient alternative. An especially attractive approach is based on solution Reynolds-averaged Navier–Stokes (RANS) equations with two-equation turbulence closure models. The validity this its inherent limitations, however, remain to be fully...
Abstract In situ visualization on high-performance computing systems allows us to analyze simulation results that would otherwise be impossible, given the size of data sets and offline post-processing execution time.

Abstract Active flow-control techniques have shown promise for achieving high levels of drag reduction. However, these are often complex and involve multiple tunable parameters, making it challenging to optimize their efficiency.

Adaptive mesh refinement (AMR) in the high-order spectral-element method code Nek5000 is demonstrated and validated with well-resolved large-eddy simulations (LES) of flow past a wing profile. In present work, around NACA 4412 profile at chord-based Reynolds number $Re_c=200,000$ studied two different angles attack: 5 11 degrees. The evolved from very coarse initial by means volume-weighted spectral error indicators, until sufficient level resolution achieved boundary wake regions....
