Mitigation of Rotating Vortex Rope in a Hydro Turbine using a Guide Vane System [Elektronisk resurs]

, 2023
Using renewable energy, such as water or wind, to produce electricity has been proven highly effective in Sweden. The ability of these renewable resources to make clean output energy counters the adversities caused by non-renewable resources.

Scale-resolving simulations of the flow in the Francis-99 turbine at part-load condition [PDF]

, 2022
In this paper, we investigate the formation of the Rotating Vortex Rope (RVR) using scale-resolving methods, SAS and Wall-Modeled LES (WMLES). We compare the results from these simulation methods with the experimental data of the Francis-99 workshop ...

Explainable machine learning for patient‐specific quality assurance in intensity‐modulated radiotherapy based on anatomical structures

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Patient‐specific quality assurance (PSQA) plays a pivotal role in intensity‐modulated radiotherapy (IMRT) to ensure accurate dose delivery. However, conventional measurement‐based PSQA approaches are labor‐intensive and provide limited insight into the underlying factors contributing to variations in gamma passing rates (GPRs ...

Microbial Metabolite‐Stimulated Bitter Taste Receptor T2R14 Signaling Is Modulated by CFTR Interactions

The FASEB Journal, Volume 40, Issue 11, 15 June 2026.
Bitter taste receptors (T2Rs) play an important role in physiological and cellular responses. Bitter tasting chemicals and microbial metabolites can bind to T2R14, which enables interactions between T2R14 and specific intracellular domains of the cystic fibrosis transmembrane conductance regulator (CFTR) anion channel.

Characteristics of Synchronous and Asynchronous modes of fluctuations in Francis turbine draft tube during load variation

, 2017
Francis turbines are often operated over a wide load range due to high flexibility in electricity demand and penetration of other renewable energies. This has raised significant concerns about the existing designing criteria.

Nonsilting transport characteristics of coal slurry in a deep underground fluidization conveying pipeline under the action of a guide vane swirler

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 539-555, June 2026.
Aiming at the scientific frontiers of in situ fluidized mining of deep resources, a deep coal fluidized pipeline lifting system based on hydraulic conveying has been proposed. To solve the issue of particle sedimentation of large particles in horizontal connection sections, a solution involving the installation of guide vane‐type swirlers in the ...
