Structures and Manufacturing
The Structures and Manufacturing Research Group is multidisciplinary and includes academics addressing a broad range of societal and engineering problems, fundamental and applied. We achieve impact through this integrated approach and by a commitment to collaborating widely with industrial and academic partners, both national and international.
Our focus on complex real-world challenges means we work with companies including BAE Systems, Qinetiq, DSTL, ITASCA, ESI, 3D Systems (CRDM), Quadra Solutions Ltd, NT CADCAM Ltd, Croft Filters Ltd. A significant portfolio of industrially-driven collaboration in the fields of engineering design and advanced manufacturing, especially with SMEs, is also enabled via both the Lancaster Product Development Unit (http://www.engineering.lancs.ac.uk/business/) and, in the area of sustainable & green technologies, the Centre for Global Eco-Innovation (http://www.cgeinnovation.org/)
Our main research areas include:
a) Sensors and Sensing techniques, advanced signal processing and structural health monitoring (Ma, Pinkerton, Ye)
Insulating material degradation diagnosis of power equipment through detection and characterisation of partial discharge activities; Metal flow visualisation by means of electromagnetic tomographic imaging techniques, Eddy current NDT testing and inspection of rail steels and porous metals. Sensors and sensing techniques, advanced signal processing and data mining techniques for structural health condition monitoring; Condition monitoring of machinery for maintenance purposes using thermal and vibration methods; Laser nanoprocessing of Fibre Bragg Gratings for enhanced functionality; Energy harvesting using piezoelectric sensor for health monitoring of green air vehicles.
b) Multifunctional Reactors and Process Intensification for Green Chemical Design(Aiouache)
3D modelling of chemical and biological processes and development of spatially resolved spectroscopic tools for 3D observations of fluid flow, mass and heat transfer trends using lasers and tomography techniques applied to reactors; Development of intensified processes for sustainable chemical processing using green ionic liquids in separation, CO2 rational use and bio-wastes conversion into liquid or gaseous fuels and into fertilisers; Design of multifunctional reactor using magnetic nanoparticles as nanomixing systems or fast thermal source or transmitter and multifunctional catalysts of dual hydrophobic and hydrophilic properties for treatment of deuteriated and triatiated waste water systems.
