Fluid mechanics for the built environment
Henry's research interests centre on the transport of heat and mass by convection, with applications to the built environment. Examples include the effective ventilation of buildings with a focus on the implications for occupancy comfort, health & well-being, & energy consumption, and to the modification of natural materials for use as structural materials in the built environment.
Recent activities have been dominated by the pandemic. To which end, Henry was ventilation lead within Task 7 of the Royal Society's 'Rapid Assistance in Modelling the Pandemic (RAMP)' and is the ventilation lead for the COVID-19 National Core Studies (NCS) programme PROTECT funded by the HSE to manage transmission in workplaces. Henry is a Co-Investigator on the EPSRC funded project CO-TRACE investigating COVID-19 transmission in schools and led the formation of CoSchools in order to ensure long-term benefits for staff and pupils from investments intended to reduce COVID transmission in schools. Henry is joint Prinical-Investigator of the Department for Education's pilot project investigating the 'Changes In the Ventilation Of Schools when monitoring CO2 (CIVOS-CO2)' funded by the Department of Health and Scoial Care. He was an invited author on the SAGE EMG paper 'Role of ventilation in controlling SARS-CoV-2 transmission' and the SAGE EMG & SPI-B paper 'Application of CO2 monitoring as an approach to managing ventilation to mitigate SARS-CoV-2 transmission'.
His ongoing work examining the fundamental effects of buoyancy on the dynamics and mixing of turbulent flows have been well received, for example, resulting in a publication in the Annual Review of Fluid Mechanics.
Henry's interests in the application of fluid mechanics to the built environment led him to found the Low-Energy Ventilation Network which he co-leads with Prof Cath Noakes. This network was supported by the EPSRC via a Special Interest Group under the UK Fluids Network. Henry is also a Co-Investigator for the Tackling Air Pollution At Schools (TAPAS) network and the Future Urban Ventilation Network (FUVN): the Breathing City (both funded under the 2020 SPF Clean Air Programme). Through these networks, and other means, Henry collaborates widely with industrial and academic partners to deliver research based impact to help shape our built environments of the future.
To support his aim, Henry remains an active member of the Natural Materials Innovation for Sustainable Living centre in Cambridge; contributing to both the group's outreach activities and research activities, by leading various projects to investigate the transport of liquids in wooden timber and trees.
His passion for science and communication keeps him involved in outreach events at all levels and led him to investigate, and ultimately disprove, the Mpemba effect - the widespread assertion that hot water cools to freezing in less time than cold. This research has been published in the journal Scientific Reports and led to research in partnership with a Sedesh high-school student which was ultimately published in the journal Proceeding of the Royal Society A.
