WebFeb 21, 2024 · According to the relaxation mechanism of nuclear magnetic resonance, the surface relaxation using water as the pore fluid is much faster than that of free … WebJul 8, 2013 · Abstract. We propose a novel device capable of measuring relaxation times of viscoelastic fluids as small as 1 ms. In contrast to most rheometers, which by their very nature are concerned with producing viscometric or nearly-viscometric flows, here we make use of an elastic instability that occurs in the flow of viscoelastic fluids with curved …

WebFeb 21, 2024 · Nuclear magnetic resonance (NMR) relaxation time provides valuable information about properties of fluid and solid surfaces within rocks; however, the complexity of rock samples makes it difficult to quantify the effect of solid–fluid interactions on NMR measurements. Additionally, the ability of 2 MHz NMR equipment to probe … WebRelaxation Process. An inverse of the relaxation process is the one in which a body or a fluid abandons the equilibrium or increases its distance from the equilibrium. …
WebComparing the diffusion and relaxation components of the uptake model of each fluid, it is clear that the main difference between them is the relaxation stage. There is a similar initial uptake for both fluids until the 200-h mark is reached, but with a very different relaxation phenomenon, which results in a much higher final sorption value ...
