Study on unsteady diffusion characteristics of primary coal and tectonic coal under the influence of pressure and particle size

Meikuang Anquan
In order to further study the characteristics of gas desorption and diffusion in coal, the gas desorption and diffusion experiments of primary coal and tectonic coal with different gas pressures (0.8, 1.3, 2.4, 3.3 MPa) and different particle sizes (0 ...

Dispersion in porous media in oscillatory flow between flat plates: applications to intrathecal, periarterial and paraarterial solute transport in the central nervous system

Fluids and Barriers of the CNS, 2019
Background As an alternative to advection, solute transport by shear-augmented dispersion within oscillatory cerebrospinal fluid flow was investigated in small channels representing the basement membranes located between cerebral arterial smooth muscle ...

UNSTEADY FLOW OF THIXOTROPIC COLLAGEN SUBSTANCE IN PIPES

Acta Polytechnica, 2015
Unsteady flow of thixotropic liquid in pipes is solved by 1D and 2D numerical methods using the same constitutive equation — the only difference is in the radial diffusion of the structural parameter.

Investigating effects from restricted diffusion in multi-component diffusion data [PDF]

, 2014
We have investigated model systems in which effects from non-Gaussian restricted diffusion could be separated from effects caused by multiple diffusion coefficients. We applied various models to analyze the experimental data.

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

Advanced Science, EarlyView.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...
