Dataset
Transition Air: Street side measurements of dispersed NO from an NO bottle in Oxford.
Abstract
This dataset contains measurements of dispersed Nitric Oxide (NO) made at a relatively low traffic area, Mansfield Road, in the city of Oxford, U.K. as part of project funded through the TRANSITION AIR QUALITY Network. NO was released from a bottle with a known concentration of 10,000ppm NO in nitrogen mounted at the back of an electric van and the dispersed NO measured at the roadside using fast response sensors provided by Cambustion Ltd. These measurements were then used to validate Computational Fluid Dynamics Models. The tests were carried out during a single day at different locations on the road. Wind direction, wind speed and the concentration of sensed NO are recorded and presented in the archived dataset.

| Access rules: |
Public data: access to these data is available to both registered and non-registered users.
Use of these data is covered by the following licence: http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/. When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |
| Data lineage: |
The measurements were performed by the hired sensing machines of Cambustion and transferred to the host institute (Oxford Brookes)via mail and emails. Then organised and analysed and uploaded to CEDA. |
| Data Quality: |
No quality standard were implemented but the sensing instruments are established to have time accuracy of milliseconds and concentration accuracy of part per billion.

| Title | Simcenter STAR-CCM+ |
| Abstract | The dispersion model hs been developed using a commercial CFD software STAR-CCM+. Simcenter STAR-CCM+ is a multiphysics computational fluid dynamics (CFD) software for the simulation of products operating under real-world conditions. Simcenter STAR-CCM+ uniquely brings automated design exploration and optimization to the CFD simulation toolkit of every engineer. The single integrated environment includes everything from CAD, automated meshing, multiphysics CFD, sophisticated postprocessing, and design exploration. This allows engineers to efficiently explore the entire design space to make better design decisions faster. https://www.plm.automation.siemens.com/global/en/products/simcenter/STAR-CCM.html |
