Turbine Blades Profile and Surface Roughness Measurement

open access: yesProcedia Engineering, 2017
Abstract The article presents the study of a turbine blade profile and roughness measurement processes - the task every manufacturer of this part needs to resolve. The blade is one of the most complex parts to manufacture because of its complex profile.

CCD-based imaging and 3D space--time mapping of terahertz fields via Kerr frequency conversion [PDF]

open access: yes, 2013
We investigate the spatially and temporally resolved four-wave mixing of terahertz (THz) fields and optical pulses in large-bandgap dielectrics, such as diamond. We show that it is possible to perform beam profiling and space–time resolved mapping of THz

Effect of 3D Shape of Pump-Turbine Runner Blade on Flow Characteristics in Turbine Mode

open access: yesJournal of Mechanical Engineering, 2022
The effect of blade spatial profiling with the help of tangential blade lean of Francis pump-turbine runner with heads up to 200 m on the flow structure and energy characteristics was numerically investigated. A flow part model of Francis pump-turbine of

Optimization of blade profiles for the Wells turbine [PDF]

open access: yesOcean Engineering, 2018
A Wells turbine, when coupled with an oscillating water column, allows the generation of power from the energy in waves on the surface of the ocean. In the present work, a tabu search is used to control the process of optimising the blade profile in the Wells turbine for greater performance, by maximising the torque coefficient. A free form deformation

Development of a robust structural health monitoring system for wind turbine foundations [PDF]

open access: yes, 2012
The construction of onshore wind turbines has rapidly been increasing as the UK attempts to meet its renewable energy targets. As the UK’s future energy depends more on wind farms, safety and security are critical to the success of this renewable energy ...

Sleep-dependent engram reactivation during hippocampal memory consolidation associated with subregion-specific biosynthetic changes

open access: yesiScience
Summary: Post-learning sleep is essential for hippocampal memory processing, including contextual fear memory consolidation. We labeled context-encoding engram neurons in the hippocampal dentate gyrus (DG) and assessed reactivation of these neurons after

Detection of surface defects in metals: a case study [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
Several approaches can be used to find defects in metal surfaces. Eddy current testing is a simple and efficient method for non-destructive testing of metals, identifying alloys, measuring coating thickness, and detecting corrosion.
