Article
With renewables as the main candidate for future energy sources, efficient energy storage is considered a key to unlock its full potential. In this context, thermal energy storage (TES), particularly molten salt-based TES, is considered as an efficient, simple and a low-cost option. One of the main drawbacks for this technology is the corrosion of...

Rain erosion on the leading edge of wind turbine blades is an intricate engineering challenge for the wind industry. Based on an energetic approach, this work proposes a methodology to characterise the erosion capacity of the raindrop impacts onto the leading edge blades. This methodology can be used with meteorological data from public institution...
Conference Paper
The rain erosion on the leading edge of wind turbine blades has become a challenging engineering issue for the wind industry during the last decades. The raindrop impacts are the primary cause of surface erosion on the leading edges. These impacts start modifying the surface roughness for later changing the shape, i.e. the aerodynamic profile, of t...
Conference Paper
The rain erosion of wind turbine blades is caused by raindrop impacts on the leading edge and is an engineering challenge for the wind industry. This erosion damage due to rainfall is directly related to the raindrop impact energy. Therefore, using an energetic approach, three different variables, namely the total kinetic energy, the kinetic power...

The evolution of the mechanical behaviour of zinc dialkyldithiophosphate (ZDDP) tribofilms on diamond-like carbon coatings during sliding contact has been studied by combining nano-indentation experimental data and finite element modelling. The nano-indentation data from the ZDDP tribofilms were obtained for two different sliding distances of the t...

The mechanical behaviour of zinc dialkyldithiophosphate (ZDDP) tribofilms on diamond-like carbon (DLC) coatings has been studied by combining the nano-indentation experimental data and finite-element modelling. Different constitutive models, whose analysis was performed using a global algorithm that consists of forward and inverse algorithms, were...
Article
Thermoplastic polyurethane elastomers under cyclic loading–unloading conditions exhibit inelastic effects, mainly stress softening, hysteresis loss and residual strain. In order to discuss the sensitivity of these effects to deformation state (uniaxial tension and pure shear) and to work conditions (maximum strain, strain-rate and stretching direct...
Conference Paper
This work presents an experimental and numerical study about the indentation behaviour under cyclic loading of an extruded thermoplastic polyurethane elastomer used as cover rope in the lift industry. The experimental contact behaviour on indentation is discussed regarding compressive load, contact area and distribution of contact pressures. The nu...

Thermoplastic polyurethane elastomers (TPUs) are a kind of elastomer that can be processed as thermoplastics. These elastomers exhibit a highly nonlinear behavior characterized by hyper-elastic deformability. Furthermore, the mechanical behavior of these elastomers is time-dependent, that is, they exhibit a viscoelastic behavior. We describe the ma...
Thesis
Full-text available
Thermoplastic polyurethane elastomers (TPU) are a class of elastomer that can be processed by heat without being destroyed. In addition to the unique mechanical performance properties of elastomers (soft, high deformation elastically, the ability to dissipate energy…), TPUs exhibit high abrasion and bending fatigue resistance. Therefore, they are u...

Since years the elevator sector is being undertaken the downsizing components (motors, sheaves...) to gain space in the systems. Due to the reduction of sheaves diameter, metallic ropes with polymeric coatings are being employed to get a significant degree of adherence between rope and sheave. There are critical gaps in knowledge about the contact...

Transform mechanical and thermal energy into electric current. * https://cordis.europa.eu/project/id/101017858 * www.electro-intrusion-eu Greenhouse gas emissions, pollution and rational energy use are civilization-scale challenges which need to be resolved urgently, in particular by the conversion of abundant waste heat and undesired vibrations into useful electricity. However, the low efficiency of existing conversion methods does not provide an attractive solution. Here we propose a new and highly efficient method and apparatuses for the simultaneous transformation of mechanical and thermal energies into electricity by using zero-emission nanotriboelectrification during non-wetting liquid intrusion-extrusion into-from nanoporous solids. To tackle these phenomena, we bring together a consortium of multidisciplinary teams specializing in physics, chemistry, material science and engineering to address the project by the state-of-the-art methods of MD simulations, high-pressure calorimetry and dielectric spectroscopy, materials synthesis and characterization, and prototype development. The FET- PROACTIVE call is a key solution to bring this early stage multidisciplinary concept to higher TRLs, fill in the large knowledge gaps in the solid-liquid contact electrification and heat generation during intrusion-extrusion as well as enable its full impact on EU innovation leadership, competitive market and energy sector security. The proposed method can be used for energy scavenging within a wide range of technologies, where vibrations and heat are available in excess (train, aviation, domestic devices, drilling, etc.). In particular, using European Environment Agency data we estimate that the use of the proposed approach only within the automobile sector can reduce the overall EU electricity consumption by 1-4% in 2050. With this regard, the final stage of the project implies regenerative shock-absorber development and field-testing for a drastic maximization of the maximum range of hybrid / electric vehicles.
Project
The WIND turbine COntrol strategies to reduce wind turbine blade Rain droplet Erosion (WINDCORE) project aims to develop wind turbine control strategies to reduce rotor speed under very bad weather conditions. This approach extends blade lifetime while energy production loss is limited. Within the project we are developing models for leading edge erosion to determine wind turbine leading edge lifetime based on amount of rain, rain characteristics and blade tip speed and validating these models through laboratory erosion testing and in-field data validation.
Project
Since wind turbines are exposed to a variety of environmental effects, e.g. rain and hail, over their operational lifetime, the wind turbine blades, mainly on the leading edge, suffer the degradation process of erosion which leads to reducing aerodynamic efficiency and power production. Therefore the reduction of the erosion on the leading edge of wind turbine blades has become an essential issue for the wind turbine industry. The main aim of this project is to establish a scientific and engineering background regarding the degradation mechanism of erosion which provides useful information to the wind industry. Therefore, the development of a new erosion test facility which properly replicates the real-life conditions of the blades under rainfall is the first goal of this project. The second goal is to study the incubation period which is the period when no significant erosion occurs, determining which variables, e.g. initial surface roughness or viscoelastic behaviour, are relevant to prolong this defect-free period. Finally, the third goal is to investigate the linear erosion period in order to obtain semi-empirical models with the capacity of prediction of erosion which will be useful for the wind industry. Moreover this third model will provide helpful information to develop new protective coating systems in order to reduce the erosion rate.
