TUSAIL is an innovative training network funded by Horizon 2020, which is comprised of 15 academic and industrial partners and led by the University of Edinburgh. Over the course of four years, TUSAIL will train 15 early-career researchers (ESRs) through a combination of PhD research, scientific training and industrial secondments. The reliable, validated simulation methodologies and tools developed in TUSAIL will be disseminated to the industry, enabling quantitative predictions of large industrial processes that will be of value for design, operation, and optimisation.
