Transportation of heavy acidic fluids is often done with specifically designed lined pipelines. The pipelines typically have an outer steel wall (thickness ~15 mm) and an inner ceramic coating (thickness ~1 mm). The proper functioning of such lined pipelines is almost exclusively determined by the inner ceramic coating. In case there would be a leak in the ceramic coating, the acidic fluid will corrode through the outer steel wall in a matter of hours, leading to a full shutdown of the industrial plant.
Upon installation of the lined pipelines, the ceramic coating could already have a varying quality: e.g. thickness variations, porosity clusters, varying stiffness,... Further, during the operational lifetime of the pipeline, the acidic fluid will gradually erode the ceramic coating (~0.05 mm/year). Hence, it is crucial to properly assess the actual state of the inner ceramic coating at certain time intervals. Current inspection procedures involve a full team of operators which need to go inside the pipeline (after thorough flushing with water) for assessing the quality of the ceramic coating.

This project focusses on the development of a novel, efficient and in-situ non-destructive test method to monitor the structural integrity of lined pipelines from the outside during their operational lifetime. The ultrasonic technique of interest is the classical contact pulse-echo ultrasound (pipelines are above the ground and accessible). From the ultrasonic response, several signal parameters will be extracted and analyzed in order to estimate the quality of the ceramic coating. In order to cope with the harsh industrial circumstances, this involves the development and implementation of (i) advanced excitation signals (e.g. coded waveforms), (ii) novel signal analysis tools in time/frequency domain and (iii) inversion procedures. In a second stage, the developed method will be implemented in a phased array system with a rolling transducer. Such a system will allow to assess large parts of the lined pipeline in a time-efficient manner.

This project requires a researcher with a strong interest in instrumental hardware (NI-PXIe platform will be employed), a good background in LabVIEW, as well as a high affinity with advanced signal processing techniques. This project is funded by industry and the final developed device will be tested on-site at the facilities of the industrial partner.

Only candidates with a Master/PhD degree in Mechanical Engineering, Electrical Engineering, Civil Engineering, (Applied) Physics or similar should apply. You are interested in instrumental physics and signal processing. You have good knowledge of LabVIEW, and preferably also of MATLAB. You are interested to interact with industry and to disseminate your results and findings.

Dear All,

I got my PhD degree of Mechanical Engineering on Sep 2016 and I am seeking PostDoc position at well-known Universitiy or research Institute. Also, I completed my short-term visiting scholar at Purdue University on March 2016.

My research interest is mechanics of advanced materials (plasticity, damage) and advanced material processing based on computaional modeling and microstructural observations. My PhD thesis was about Ultrasonic assisted ECAP based on constitutive equation developed for compression behavior of aluminum under high-intensity ultrasonic excitation. I designed, analyzed and fabricated two experimental setup for both ultrasonic assisted compression test and ultrasonic assisted ECAP.

Also, I have seven years industrial experineces in design, FE analysis and manufacturing of mechanical components in steel making and pelletizing plants.

Please contact me for sending my CV and discuss more about research interestes.

Research interests of this groupare focused primarily on characterization of materials and microstructures atmultiple scales using ultrasound, nanoindentation, and atomic force microscopy.The wave propagation research is primarily associated with heterogeneous mediafor which deterministic analysis techniques are either unsuitable or toodifficult. Statistical approaches are used for obtaining importantmicrostructural information about these complex materials which include polycrystallinemetals, composites, concrete, geophysical materials, and biological materials.This work has both theoretical/numerical and experimental aspects for materialscharacterization and nondestructive testing purposes. The group is also studyingthe mechanics of nanoscale materials characterization using the atomic forcemicroscope (AFM) and nanoindentation. Of particular interest are dynamictechniques that can be used to extract viscoelastic properties. The group hasstrong U.S. and international collaborations with universities, researchinstitutes, national labs and industry. For more information please visit http://em-jaturner.unl.edu/.
