The Department of Mechanical, Manufacturing and Biomedical Engineering in Trinity College Dublin requires the supply, delivery, installation, and commissioning of an advanced 2D/3D Particle Image Velocimetry (PIV) and Digital Image Correlation (DIC) system to support cutting-edge experimental research in fluid dynamics and solid mechanics. The system shall comprise a high-energy pulsed laser, synchronised high-resolution cameras, precision timing and control units, and fully integrated acquisition and analysis software. The solution must be capable of capturing high-accuracy, time-resolved measurements of velocity fields, particle motion, and surface deformation, enabling two-dimensional (2D) and ideally also three-dimensional (3D) analysis. It should support applications involving complex flow regimes, multiphase flows, and structural behaviour under varying conditions. Flexibility for future upgrades is essential, including the potential to incorporate temperature and scalar concentration measurements. The equipment must demonstrate proven reliability, accuracy, and repeatability, and be suitable for intensive research use. Full installation, calibration, commissioning, and user training are required, along with comprehensive documentation and ongoing technical support. The system must integrate seamlessly with existing laboratory infrastructure and contribute to enhancing the Department’s research capabilities and output.
