Summary on Grant Application Form |
|
Diffusion and fluid flow behaviour in heterogeneous systems, typified by fluid phases in porous solids will be extended through theoretical and experimental investigations. Pulsed magnetic field gradient (fgp) and spin echo (pgse) methods will be the main focus. Three main themes will be pursued. Firstly, derivation of structure and fluid phase size scales and other characteristics for systems exhibiting restricted diffusion, surfaceenhanced relaxation and internal magnetic field gradients, will be addressed. Typically, the use of multiple/alternating fgp phase labelling will be considered, to understand more fully the way in which the observation time is affected by this approach (designed to minimise effects of internal gradients). In addition, the possibilities for better definition of fluid transport through time-correlated effects in such multiple fgp sequences will be explored. Secondly, investigations will be undertaken of the response to pgse-type experiments of fluids flowing through structures which impose time variation on the velocity fields. q-space effect, analgous to those demonstrated for diffusion will be investigated and a velocity correlation function description developed alongside experiments covering a wide range of observation times. Thirdly, experimental investigation of systems having two immiscible fluid phases within a solid matrix. Static, time varying and dynamic steady states will be examined and the use of quadrupolar spins such as 23Na and 35C1 investigated.
