Atmospheric implications of untested carbonyl photochemistry: an evaluation using chemically explicit and global 3D modelling
… range of values on the production of HFC-23. The modelling estimates show that CF3CHO could contribute up to 14.7% to the current HFC-23 global growth rate. Finally, a new mechanism called photophysical oxidation (PPO) in carbonyls was also studied using acetaldehyde as a benchmark compound. In …

How did the Human Brain Evolve? Tracking Cerebral Changes in the Fossil Hominin Record Using Advanced Imaging Techniques and 3D Modelling
Understanding the evolution of the hominin brain is critical for reconstructing the emergence of human cognitive abilities. However, given the lack of direct fossilised brain tissue, palaeoneurological studies rely on cranial endocasts, replicas of the internal surface of the braincase, to infer …

Bridging local and external knowledge for disaster risk management planning: The perceived benefit of participatory 3D modelling in Umgungundlovu District Municipality, South Africa
… building and using three-dimensional models (P3DM) has been used internationally to enhance community engagement and to ensure better information exchange between people who live in the area and the disaster officials and consultants who currently inform decisions. P3DM was introduced in …

3D modelling by computational fluid dynamics of local interactions of momentum, mass and heat transfers with catalyst deactivation in gas-solid catalytic reactors of low aspect ratios
… investigations for the development of 3D modelling codes by computational fluid dynamics are still not sufficiently mature compared with those relying on 2D modelling or simplified pseudo-homogenous models. This project investigates non-uniform catalyst deactivation in packed bed …
