EnFlo, the Environmental Flow Research Centre, was established in 1993 as a focus for UK research activities based on laboratory scale simulation of atmospheric flow and pollutant dispersion. It is a NERC-NCAS Centre for Atmospheric Sciences and a member of the UWERN and APRIL research networks.

EnFlo was established by the donation of two major facilities, a wind tunnel and a towing tank, by National Power plc to the University. Both can be operated in a density stratified mode, which gives the laboratory a unique experimental capability and also permits a very wide range of environmental conditions to be modelled. The wind tunnel has a 20m long working section, 3.5x1.5m in cross section, and is stratified by differential heating of the incoming air, together with heating and cooling of the tunnel walls. The 12m long towing tank has a 1x1m cross-section and is stratified by mixing fresh water and brine during its filling.

The Objectives of the Centre are:

o to provide Wind Tunnel and Towing Tank facilities in support of research on fluid flow and dispersion which, through their unique capabilities, will enhance the competitiveness of UK environmental scientists in both academic and industrial spheres;

o to undertake research on flow and pollutant dispersion processes in the earth's atmosphere, oceans, lakes and rivers, which will lead to improved modelling and assessment procedures;

o to provide training and promote good practice in the use of laboratory modelling techniques in environmental fluid mechanics;

o to provide the required user support to the community;

o to ensure that proposed research is assessed through appropriate review procedures so as to maintain the desired level of scientific excellence.

In order to achieve these objectives we will:

o provide appropriate access to researchers throughout academia and industry;

o maintain its major flow rigs and undertake a programme of continual development of the associated instrumentation capabilities;

o disseminate information to the wider scientific community via publication, conference presentation, short courses and workshops;

o maintain an awareness of the users' real requirements;

o monitor the users' satisfaction with the service provided;

o seek commissioned work to supplement the centre's income as necessary.
