AIR SCIENCE COUNTERING COVID-19 SPREAD
In June 2020, Twin Dynamics realised the role airborne transmission of aerosol will play in spreading the virus. This early realisation came through an outbreak that occurred in a restaurant based in Guangzhou, China. On investigation, airflow patterns due to air conditioning was documented as a crucial factor for the outbreak. Twin Dynamics immediately started working towards an air science solution to make indoor spaces resilient to such outbreaks. In September 2020, Twin Dynamics secured UK government funding to accelerate the development of a technology to tackle the spread of coronavirus in indoor spaces. After six months of the development, Twin Dynamics is proud to present digital twin technology that offers to track respiratory droplets and aerosols spreading within indoor spaces.
Bringing The Power of Digital Twin
Our patent pending digital twin technology maps centimetre by centimetre the airflow and thermal insights within indoor spaces. It is this expert mapping which helps in tracking the spread of respiratory droplets and aerosols. It is known that heavier droplets may travel two metres before settling down. However, the lighter micro-particles (aerosols) tend to be suspended in air for longer time, thus increasing the risk of exposure.
Our digital twin technology aims to answer:
in which direction the heavier particles will travel and what surface might get contaminated?
where will aerosols be circulated to and how will they re-circulate because of ventilation systems?
Answering these questions dramatically reduces the risk of cross infection. Our digital twin based services are designed to help counter risks and are tailored to particular needs.
Our Digital Twin based services are helping customers comply with ISO/PAS 45005:2020 Health and Safety standard
Our digital twin services are also focused to help customer adhere to ISO/PAS 45005:2020 standard. Work-related health and safety management is of a greater concern, specifically during this pandemic.
Some specific points of interests from ISO/PAS 45005:2020 standard:
Section 4.1.1. dictates the risks are to be mitigated on an ongoing basis.
Section 220.127.116.11e. it is advised to enhance cleaning and disinfection schedules.
Section 8. recommends the use of 'technology' to effectively manage the risks related to COVID-19 for starting and maintaining organizational activities.
Our digital twin services are focused to aid customers comply with the health and safety regulations and to have sustained reopening during pandemic.
HOW DO WE GENERATE DIGITAL TWIN
Collecting indoor space layout plans and HVAC sensor data
Generate CAD model of the indoor space and perform engineering simulations
Generate big data from engineering simulations on air/thermal flow distribution within indoor space at various operational conditions
Input the generated big data through digital twin algorithm to construct mirrored computer replica of the indoor space
Connect the digital twin and the indoor space to our TwiDy platform over the cloud
