Experimental and numerical investigation of a compressor cascade at highly negative incidence [PDF]
, 2011 The performance prediction of axial flow compressors and turbines still relies on the stationary testing of blade cascades. Most of the blade testing studies are done for operating conditions close to the design point or in off-design areas not too ...

A Global Design Search of a Shrouded Tidal Current Turbine by Meta-model Assisted Genetic Algorithms
International Marine Energy JournalThis study was conducted to investigate the effect of geometry on the performance of a shrouded tidal turbine. When the hub radius and taper change, with a fixed shroud radius, the inlet area changes from the inlet to the turbine, and according to the ...

Variable turbine geometry for an automotive turbocharger with a small axial turbine
Proceedings of Global Power & Propulsion SocietyThe paper examines the implementation of a variable turbine geometry (VTG) and the reduction of its tip leakage losses in a small axial turbine turbocharger for charging lean-burn internal combustion engines. Due to the small turbine size, a reduction in the number of vanes and a redesign was required to match the design point of the non-adjustable ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

Quality and Reliability Engineering International, EarlyView.ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.

Theoretical and experimental study of turbine flowmeters [PDF]
, 1992 A vortex shedding model is developed to predict the flow fields around turbine flowmeter blades. This model is used to simulate the flow separation and reattachment in the leading edge areas and the wake flows of the blades.

Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Thermal Modelling of the Ventilation and Cooling inside Axial Flux Permanent Magnet Generators [PDF]
, 2010 Axial flux permanent magnet generators are of particular interest for power generation in harsh and confined conditions. Due to their compactness and high power density, the ventilation and cooling inside axial flux permanent magnet generators have ...

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel
River Research and Applications, EarlyView.ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...
