Today @UKFluidsNetwork and @FluidsLeeds launched a new report looking at the importance of fluid dynamics in the UK and how we can support the next advances in this diverse discipline.
A short thread on the conclusions 1/
Fluid dynamics is everywhere – the air we breathe, water we drink, products we use. Fluid dynamics is an enabling technology for a vast number of industries 2/
Fluid dynamics contributes over £13.9billion annually to the UK economy. Industries which rely ofn fluid dynamics have a total output of over £200 billion. 3/
Fluid dynamics activity in the UK has a global influence with 70% of firms exporting and more than 1/3 with over 50% of their activity in exports 4/
Fluid dynamics is a whole nation activity with employment, output and gross value added distributed right across the UK. This includes academia with over 75 universities involved in fluid dynamics research 5/
Fluid dynamics activity is underpinned by a substantial research base. Since 2012 @UKRI_News have funded over 3,600 fluids related grants worth £3.2 billion 6/
Fluid dynamics impacts on major societal challenges and the impact of this is immeasurable. Key areas include net-zero, future transport, high value engineering and healthcare 7/
To deliver the next advances in fluid dynamics and deliver transformational change we need to work together as a community across research and industry. The report makes four key recommendations 8/
1.Creating a National Centre in fluid dynamics. This would build on practitioner networks and UK research strengths through the @UKFluidsNetwork to act as a hub to bring people together 9/
2.Increased support for fluid dynamics training in industry and academia. Fluid dynamics is a highly skilled profession which requires postgraduate level expertise and strong CPD. 10/
3.The application of next-generation data driven fluid dynamics methods across sectors and into industry. This will enable more efficient processes as well as advance fundamental understanding 11/
4.Generation and retention of fluid dynamics intellectual property and expertise in the UK. Attracting and anchoring major R&D hubs in the UK can deliver world leading innovation 12/
A Sunday thread on ventilation metrics and exposure as they are not quite as straightforward as you may think 1/
Under steady state conditions (ie people have been in the space for a while and the ventilation is constant) then concentration in the air of anything that remains airborne (CO2, the smallest virus particles) is emission rate divided by total ventilation rate 2/
The total ventilation rate is the total volume of fresh air provided to the room, which is normally measured in m3/s, l/min or a similar metric. You can also get this from the ventilation rate per person (l/s/p) multiplied by the number of people 3/
A thread today about windows and ventilation, and some things you can do to make the most of your windows for comfort and infection risk 1/
First, you will probably use them differently at different times of the year and in different weather conditions. That’s because natural ventilation works in two ways 2/
Wind driven ventilation uses wind blowing onto a building to create a pressure difference across a building. This difference in pressure moves air into and through the building. 3/
Now more business are going to have more people in them ventilation becomes an even more important mitigation strategy
You can use CO2 monitoring to help.
Here's another thread that may be useful if you are looking to use CO2 1/
You use a CO2 monitor for a short period to check the ventilation in an occupied space. This would often be done by facilities management and is a good check in regularly occupied spaces with constant mechanical ventilation 2/
You can also have a monitor displaying all the time and use it to actively manage the ventilation – this is good where you have opening windows or other controls that people in the room can use 3/
