About the project
This project aims to revolutionise the understanding of fluidic flows through the use of hyperspectral imaging techniques.
Currently, the most-promising development in non-intrusive measurement of surface pressure or temperature is the use of luminescent pressure-or temperature-sensitive paints (PSPs or TSPs). PSPs overcome the challenges associated with traditional ‘invasive’ single point pressure sensing technologies by relating a luminescence change of a small molecule in a porous matrix to the local partial pressure of oxygen. Similarly, temperature sensitive luminophores can be used to measure local surface temperature. The paint-like application means that large areas of models or equipment can be coated and imaged without the need for any high-temperature thermal bonding (unlike for thermographic phosphors).
The simultaneous, accurate, and, most importantly, non-intrusive measurement of unsteady surface pressure and temperature over large areas and extended time periods, a capability not currently possible, is essential to increase fundamental understanding of fluid flows. Such understanding leads to improved aerodynamic designs and development of novel components and engineering strategies.
By employing hyperspectral imaging capabilities, the aim is to create a multifunctional engineered smart coating that can be applied to any surface. By exploiting the engineered effects on the nanoscale to measure fluid dynamic effects on the macro-scale the understanding of fluidic flows can be revolutionised. This will enable the development and testing of highly efficient fluid dynamic components where installation of multiple sensors is impracticable, or too costly.
Funding for this project is offered by the Centre for Doctoral Training in Complex Integrated Systems for Defence & Security (CISDnS), which will recruit motivated and inquisitive candidates across the themes of digital, physical and biological systems to provide a diverse and interconnected cohort training environment.
