Centre for Aerodynamics & Environmental Flows

A particularly important application of combined ground based meteorological and atmospheric pollutant concentration measurements is the evaluation of emission rates from a range of industrial and other sources. For example, losses to the atmosphere from leaks at chemical process plant are notoriously difficult to quantify yet have a major impact on plant operations, safety and environmental impact. For a number of practical reasons, measurements are generally made close to sites of interest where the flow field tends to be complex, making interpretation on measurements difficult and potentially introducing large uncertainty into estimates of loss rates. Understanding and reducing these uncertainties lies at the heart of improved measurement techniques.

The overall aim of the proposed research is to develop a better understanding of the nature of the concentrations measured by Differential Absorption Lidar (DIAL) and other path-integrating instruments, and how these relate to the well understood physics of point concentrations. The work will also address issues that arise from the complexity of the wind fields in which pollutant flux measurements are often conducted and the uncertainty that accrues in derived emission rates. Both laboratory (wind tunnel) and field work (NPL DIAL) will be used to investigate these issues. The scientific understanding derived from this work will lead to protocols and quality assurance guidance for field work that take account of the complexity of the flow field and are intended to minimise as far as possible the uncertainty in field estimations of pollutant fluxes, as well as giving some indication of the level of those uncertainties.

The research will address flows of increasing complexity so that the uncertainty can be related to the flow conditions and optimal methods and procedures identified. The work will make extensive use of the University of Surrey EnFlo wind tunnel, which can be used to simulate the dispersion of pollutants in the atmosphere under a wide range of flow and emission conditions. There will also be opportunities to join the NPL team in field work that will provide test cases that can later be modelled and investigated in detail at wind tunnel scale. Experimental work will be supported by analysis and computational studies.

The Environmental Measurement Group at NPL provides high quality, pollution monitoring and analysis research and measurement services. It has long-established, expert knowledge of the use of remote sensing techniques to solve complex atmospheric measurement problems. NPL has invested over £1M in a new mobile research facility that is being used around the world to identify and quantify methane, non-methane VOCs and benzene fugitive emissions from a wide range of commercial facilities, including gas facilities, refineries, steel works and landfill sites. The information obtained with DIAL measurements allow site operators to identify significant fugitive emission sources informing operational efficiency, reducing losses and supporting research and policy developments.

The Aerodynamics & Environmental Flow Research Group in the University of Surrey Department of Mechanical Engineering Sciences (MES) has an excellent collaboration network with leading research groups in the UK and internationally. The student will benefit from links with other projects current in the research group, in particular MAGIC (managing air in green inner-cities); www.magic-air.uk.

In working with leading scientists at both NPL and the University, the student will gain detailed knowledge of flow and dispersion in the atmosphere, and the wind tunnel and field methods used to investigate the underlying physical processes. Knowledge will be broadened by association with other projects in progress at the NPL Environmental Measurement Group and at EnFlo, as well as through the Scenario programme as a whole.

This project has been selected for funding by the SCENARIO panel. The process is still competitive: twice as many projects have been selected than the funding allows- the final selection will depend on the quality of the individual applicants. 

This project is funded through the SCENARIO Doctoral Training Partnership, a collaboration between NERC, the University of Surrey and the University of Reading.

PhD position in quantum optimal control theory at the University of Bourgogne

This PhD project aims at applying innovative mathematical tools coming

from optimal control theory to improve theoretical and experimental techniques

in Nuclear Magnetic Resonance (NMR), in Electron Spin Resonance (ESR) and in NV

centers. This approach will allow us to explore and to experimentally reach the

physical limits of the corresponding spin dynamics in presence of typical

experimental imperfections and limitations. A first objective will be to

develop new optimal control algorithms able for an inhomogeneous ensemble of

spins to maximize the signal to noise ratio per unit time of the system. A

general problem is to generalize the Ernst angle solution used in NMR, which is

only valid for a homogeneous spin ensemble. This work will be done in

collaboration with the group of S. Glaser (TUM, Munich, Germany). This approach

will find different applications in NMR and ESR where the sensitivity of the

experiment is a crucial parameter. The student will focus on a specific

experimental setup in ESR used by the group of P. Bertet (CEA, Paris Saclay),

where an important goal is the maximization of the emitted signal of spins

coupled to a microwave resonator. The student will take into account in the

numerical computation specific constraints of this experimental setup. In the

same direction, the student will also use optimal control techniques to design

new CMPG sequences accounting for the coupling between the spins and the

cavity. The same types of control techniques will also be used for manipulating

NV ensembles in collaboration with the group of T. Debuisschert (Thalès,

Check out  PhD Position in Causal Data Science

Paris). This will allow the improvement of the sensitivity of the corresponding

experiments. For a more fundamental point of view, the ESR will investigate the

numerical techniques used to design robust control fields with respect to

experimental imperfections. A first objective will be to understand the

efficiency of these methods and to prove the optimality (this concept will be

to define rigorously) of the control fields. The ESR will mainly study spin

systems but it is clear that the results of this project will not be restricted

to the physical systems investigated and the techniques developed during the

PhD could be applied to other physical systems with similar properties.
