Multi-scale assessment of residual structural capacity of deteriorating reinforced concrete structures. KU Leuven
Analysis and mitigation of pressure fluctuations in compressors KU Leuven
Compressors are used worldwide in various applications: from compressing air that is used to power pneumatic tools, to compressing a refrigerant in a cooling installation. Inside a compressor, gas is aspirated at a low pressure, compressed and then discharged at a higher pressure. During the suction and discharge process, the unsteady mass flow creates pressure fluctuations in intake and exhaust systems. These pressure fluctuations can be ...
Development and validation of a wave based technique for forward and inverse simulation of vibro-acoustic problems with trim material damping. KU Leuven
In recent years, the vibro-acoustic performance of products has become a key design feature. This evolution has been instigated by growing customer expectations, who associate the sound of a product with a certain quality, and by ever tightening regulations on the noise emission levels of products and the human exposure to noise and vibrations. Another important is the trend towards lightweight materials, fuelled by an increasing ecological ...
Integration of damping in wave based simulation models for mid-frequency vibro-acoustic analysis and design. KU Leuven
Simulation supported vibro-acoustic monitoring of additive manufacturing parts KU Leuven
This PhD is part of a project called “MUSIC” aiming to produce first-time right zero-defect parts through additive manufacturing. This project aims to develop monitoring solutions fusing complementary information from optical sensors, and structural and airborne acoustic emission sensors. Given the complexity of combining different monitoring data streams, the project will employ data-driven models as well as physics-based signal analysis. ...
Aeroacoustic design and analysis of advanced light-weight liner configurations for sound attenuation in ducted flows. KU Leuven
Flow duct systems, such as automotive exhausts and ventilation systems, are an important source of noise disturbance. These systems not only contain significant sources of sound, but also act as an efficient transfer path for the noise generated upstream. Because of the growing customer expectations and the restrictive legal requirements regarding the noise emission to the environment, the need for efficient characterization and prediction ...
Aeroacoustic Feedback Phenomena in Side-Branch Helmholtz Resonators: a Numerical and Experimental Analysis KU Leuven
The research project focuses on the investigation of aeroacoustic feedback phenomena in a flow duct component and their influence on far-field noise radiation by means of numerical and experimental analysis. Constructive feedback interactions between the aerodynamic and acoustic fields cause aeroacoustic instabilities resulting in self-sustained pressure oscillations of high amplitude that can cause severe noise emissions (i.e., whistling). A ...
Multi-layer Bayesian life-cycle methodology for the structural assessment of existing concrete structures (lifeMACS) KU Leuven
Repair and upgrading of structures are becoming increasingly important and are associated to an increasing part of activities in the construction sector. Current state of the art lacks a coupled Bayesian framework that enables to update through-life performance predictions, optimize inspections and interventions and fully exploit knowledge available through information gathered or modelled, limiting the exploitation of the benefits of ...
FemtoFac: Femtosecond pulse laser Facility for micro & nanoscale research. KU Leuven
This project is about acquiring a state-of-the-art femtosecond pulse laser micromachining platform and developing research activities using this novel micro and nano fabrication tool. With its ultrashort pulse width and extremely high peak intensity, a femtosecond laser can produce high quality small features with micrometer resolution as well as nano-features. Furthermore, it can do so with very limited thermal damage and material ...
