Current Funded Research Projects
Start: 15-04-2021 / End: 14-04-2023
The aim of this project is to develop an air filtration system for the Indian subcontinent with heavy pollution settings, while having air infection risk. Strategies of deployment and usage will be developed along with training of UK and Indian students, and knowledge transfer with industry with overall UK & India budget of £80k.
Start: 20-03-2019 / End: 19-03-2022
High fidelity flow-structural dynamics simulations of wind and water turbines will be pursued using advanced computing clusters and complemented by wind tunnel tests. The results will be analysed and used to derive new fast models that will support future development of new renewable energy devices extracting kinetic energy from the wind and water flows.

The devise utilises a novel particle separation technology, which boosts the air disinfection capabilities of an ultraviolet-C (UV-C) light source, allowing much larger quantities of air to be purified than would normally be the case. If successful, the device will represent a step-change on current air disinfection technologies and should prove helpful in combating the transmission of airborne0 (aerosol) diseases such as Covid-19 and TB within buildings. Light in the UV-C region produces photons that are absorbed by nucleic acids (both DNA and RNA) to form dimers (fused base pairs) that impair replication of pathogenic viruses and bacteria , greatly reducing their ability cause infection. It has been shown that UV-C light can inactivate coronaviruses and thus there is good reason to believe that the SARS-CoV-2 virus will be susceptible to UV irradiation . Similarly, it has been shown that TB can be inactivated using UV-C light . Both TB and Covid-19 are infectious diseases that are transmitted via aerosolised respiratory droplets produced indoors. As such, UV-C air disinfection devices have great potential to inhibit the spread of these diseases in room spaces if used appropriately. However, such devices are limited by the small air flow rate that they can handle. This is because pathogenic microbes often require high UV irradiation doses, with the result that the air velocity through such devices needs to be very low, meaning that they can only disinfect small amounts of air. However, by utilising particle separation it is possible to greatly enhance the irradiation capabilities of the device, thus allowing much larger quantities of air to be disinfected.
