Abstract In the pre-construction phase of offshore wind energy projects floating lidar systems (FLS) are used for site assessment. Their measurements mean speed and direction have proven to be accurate according existing standards. But assessment turbulence intensity (TI), a widely-accepted procedure acceptance criteria missing. This study investigates different evaluation methods, namely linea...

INTRODUCTION Turbulence, characterized by velocity fluctuations, is a sign of suboptimal hemodynamics in prosthetic heart valves [1]. Turbulence causes pressure drops and exposes endothelial cells and blood constituents to abnormal stresses which can lead to blood trauma and promote the pathogenesis of atherosclerosis. Phase-contrast MRI (PC-MRI) has previously been shown to be valuable for the...

Calanoid copepods represent a major component of the plankton community. These small animals reside in constantly flowing environments. Given the fundamental role of behaviour in their ecology, it is especially relevant to know how copepods perform in turbulent flows. By means of three-dimensional particle tracking velocimetry, we reconstructed the trajectories of hundreds of adult Eurytemora a...

Project Overview Interrupted-fin surfaces are used to enhance the air-side heat transfer performance in many compact heat exchangers. While many empirical correlations are available in the open literature for offset-strip and louvered-fin geometries, local heat transfer behavior on individual fins is not as well understood. A redesign of these surfaces may result in higher heat transfer. Inlet ...

The European program HORIZON2020 aims to have 20% of electricity produced by renewable sources. The building sector represents 40% of the European Union energy consumption. Reducing energy consumption in buildings is therefore a priority for energy efficiency. The present investigation explores the most adequate roof shapes compatible with the placement of different types of small wind energy g...
