Full textThermal fatigue occurs in nuclear power plant pipes. The temperature variations are due to the turbulent mixing of fluids that have different temperatures. Many experimental setups have been designed but the measured temperatures have only been punctual and out of the zone of interest (e.g., via thermocouples). The equivalent strain variation in the crack initiation region is calculated with numerical thermomechanical simulations. In many cases, the comparisons between numerical and experimental results have shown that the crack initiation predictions in thermal fatigue are non-conservative. A new testing setup is proposed where thermal shocks are applied with a pulsed laser beam while the thermal and kinematic fields on the specimen surface are measured with infrared (IR) and visible cameras, respectively. Experimental testings are performed and different measurement techniques for temperature and kinematic fields are used. IR camera and pyrometers allow to measure the temperature variations in the zone impacted by the laser beam. To estimate the absolute temperature, the surface emissivities at the respective wavelengths are determined by different methods. The absolute temperature field is then used to apply the actual thermal loading in a decoupled FE model after an identification process of the parameters of the laser beam. Once the thermal loading is generated based upon the experimental data, the stress and strain fields can be computed in the region of interest with an elastoplastic law.The experimental strain variations calculated from the DIC measurements are compared with the predictions obtained with the FE simulation

Full textIn highly dissipative contacts, the energy dissipated by friction leads to severe thermal loads which could have bad consequences on performances, on friction parts durability, on the environment or on human health. Therefore, knowledge of sliding surfaces thermal fields is a first-rate issue. Due to the lack of knowledge about the emissivity of those surfaces, which change both spatially and temporally during friction, measuring thermal fields is difficult. The work done concerned the development of thermal fields measurement by bispectral thermography, which allows to get simultaneously surface emissivity and temperature. The difficulties reside in the spatial and temporal images registration of two infrared cameras, in the camera flows calibration and in the spectral emissivity variation. The technique developed was applied to the in situ fields measurement of temperature and emissivity of a brake disc during braking. It was then used for analysis of thermal locations induced by friction and their interactions with the tribological circus, leveraging the knowledge of the spatial and temporal evolution of the emissivity

Full textThis study is a contribution to the comprehension of high pressure boiling flows relative to PWR.The first part exposes a two-dimensional unsteady state model in order to predict the development of a boiling flow in a circular pipe. The local mixture balanced equations are used with a relaxation model to close the vapor production rate (local homogeneous relaxation model). The results obtained from the comparison with the data bank DEBORA reveal a good qualitative agreement. Nerveless, the model is currently unable to correctly describe radial transports of turbulence and vapor fraction from the heated wall to the center of the pipe.The second part deals with the use of hot wire anemometry in experimental loop DEBORA to provide radial distributions of mean liquid velocity, mean liquid temperature and void fraction in a boiling flow. Classical hot wire probes are used (DANTEC@ hot film and hot wire probes) and are driven at different overheats using a constant current anemometer. Some measurements are first performed in single phase heated flows. Then, a phase identification procedure is developed, and some boiling flow measurements are obtained and compared with the model

Full textThe present thesis aimed to apply digital image correlation (DIC) used for kinematic fields’ measurements as a support for the experimental characterization of refractory materials with specific non-linear behaviour. Model and industrial materials with different degrees of flexibility were studied. The first type of materials was a single phase model flexible aluminium titanate material (AT VF) developed for academic purposes by improving the grain growth. Its non-linear mechanical behaviour was obtained thanks to the thermal expansion mismatch of its grains according to the different crystallographic axis. The second one is multi-phased magnesia based industrial materials, whose flexibility is less accentuated, and for which the non-linear mechanical behaviour is obtained thanks to the thermal expansion coefficients mismatch between spinel aggregates and magnesia matrix. In order to apply the optical methods on these materials which exhibit lower strain-to-rupture, it was necessary to optimize the accuracy of these techniques by improving experimental conditions.In the case of AT VF, DIC and mark tracking method have been applied on four-points bending test at room temperature to underline the material asymmetric mechanical behaviour which induces a significant shift of the neutral fibre and to evaluate the relative displacement of rolls. The application of DIC has been extended to other experimental testing method such as Brazilian and Wedge Splitting test using the multi-phased magnesia based materials. This highlighted fracture mechanisms (crack occurrence and propagation) and the presence of crack branching phenomenon promoted thanks to an initial micro-cracks network voluntary introduced by thermal expansion mismatch between the different phases so as to improve their thermal shock resistance. From displacement experimentally obtained by DIC, a finite element method updating (FEMU-U) has been developed to determine material properties

Full textSolid dielectrics are basic elements of most insulations used in devices or systems in electrical engineering or in power electronics. Mainly due to current trends in downsizing, these insulations being subjected to increasing stresses (electrical, mechanical or thermal) may degrade and age dielectrically. This may lead to failure and breakdown, which have to be addressed. More specifically, the global charge store inside the dielectric and generally called space charge is directly linked to these degradation processes. It is therefore necessary to analyze this space charge behavior when the material is at the same time stressed under conditions close to those of the real environment of use. Among many existing techniques, the (F)LIMM is a thermal wave method dedicated to the space charge analysis of thin dielectric films (with a thickness from 5µm to 50µm), with a possibility of 3-D cartographies when the beam is focused onto the sample under study. Its first characterizations were related to the determination of the space charge distribution in thin films that were first submitted to an external DC field and next analyzed in a volt-off way (no voltage applied). This off-line procedure remained the only way of space charge investigations for quite a while. New developments became necessary in order to provide answers to the industry for which a characterization close to the actual conditions of use was lacking. For this purpose, an on-line version of the conventional (F)LIMM set-up was developed. It allows a measurement of the (F)LIMM current when simultaneously a DC bias field is applied to the sample. This development presents, apart from allowing an in-situ and on-line analysis, another important advantage, namely the possibility for assessing or calibrating the temperature profile. In this work, the experimental modifications made to the measuring test rig are first detailed and validated. Then, the calibration procedure of the thermal model developed is explained and tested. As a consequence, the possibility of simulating the (F)LIMM currents is possible and shows a very good agreement with the experimental registered ones. Finally, some applications to PEN and PP polymer thin films are described and results got prove the efficiency of these new developments for space charge on-line investigation
