Manning's Formula and the Strickler Scaling Derived from a Co-spectral Budget Model
Gabriele Manoli, Sara Bonetti, Gabriel George Katul
Manning's empirical formula in conjunction with Strickler's scaling is widely used to predict the bulk velocity (V) from the hydraulic radius (Rh), the roughness size (r), and the slope of the energy grade line (S) in uniform channel flows at high bulk Rey ...
2023Quantifying the Solution Structure of Metal Nanoclusters Using Small-Angle Neutron Scattering
Francesco Stellacci, Stefan Guldin, Ye Yang, Zhi Luo, Huayan Yang
Metal nanoclusters are a unique class of synthetic material, as their crystal structures can be resolved using X-ray diffraction, and their chemical formula can be precisely determinated from mass spectroscopy. However, a complete structure characterizatio ...
WILEY-V C H VERLAG GMBH2022Improved Natural-Air-Convection-Cooling Formulas for Medium Frequency Transformer Design Optimization
Drazen Dujic, Marko Mogorovic, Jonas Piet K Le Roy
This paper provides accurate analytic models for a computationally efficient estimation of the natural con- vection cooling coefficients for typical geometries, such as those encountered in transformers. Proper thermal coordination is an essential step of ...
2021Thermal spin crossover in Fe(ii) and Fe(iii). Accurate spin state energetics at the solid state
Sergio Vela Llausi, Maria Fumanal Quintana
The thermal spin crossover (SCO) phenomenon refers to an entropy-driven spin transition in some materials based on d(6)-d(9) transition metal complexes. While its molecular origin is well known, intricate SCO behaviours are increasingly common, in which th ...
ROYAL SOC CHEMISTRY2020Discovery of a self-healing catalyst for the hydrolytic dehydrogenation of ammonia borane
Emad Oveisi, Mounir Driss Mensi, Fatmah Ebrahim, Kyriakos Stylianou, Ngoc Tú Nguyên, Andrzej Gladysiak, Bardiya Valizadeh, Fatma Pelin Uran
Sustainable catalysts based on earth-abundant elements are considered as economical alternatives to precious-metal-bearing catalysts and could be impactful for many applications. Self-healing sustainable catalysts, which in addition to their 'green' charac ...
2019From experimental evidence to mechanical modeling and design expressions: The Critical Shear Crack Theory for shear design
Aurelio Muttoni, Miguel Fernández Ruiz
Many research efforts have so far been devoted to the topic of shear design of members without transverse reinforcement since the first development in structural concrete. This has allowed a number of significant advances in the understanding of the phenom ...
2019Early Stages of Precipitation In Aluminum Alloys by First-Principles and Machine-Learning Atomistic Simulations
Age hardening induced by the formation of (semi)-coherent precipitate phases is crucial for the processing and final properties of the widely used Al-6000 alloys despite the early stages of precipitation are still far from being fully understood. This cruc ...
EPFL2018Photoanode/Electrolyte Interface Stability in Aqueous Dye-Sensitized Solar Cells
O'Regan and Gratzel conceived a dye-sensitized solar cell (DSSC), which operates as an artificial photosynthetic system converting solar light into electricity. Nevertheless, it is only recently that the scientific community is focusing on truly aqueous DS ...
Wiley-V C H Verlag Gmbh2017Manning’s formula and Strickler’s scaling explained by a co-spectral budget model
Sara Bonetti, Gabriel George Katul
Manning’s empirical formula in conjunction with Strickler’s scaling is widely used to predict the bulk velocity V from the hydraulic radius Rh, the roughness size r and the slope of the energy grade line S in uniform channel and pipe flows at high bulk Rey ...
2017Calculation of the General Number of Imposed Constraints of Kinematic Chains
The study provides derivation and application of novel formula for the calculation of general imposed constraints for kinematic chains (including mechanisms and zero-degrees-of-freedom Assur groups) depending on the types of kinematic pairs and numbers of ...
