Bed-design characteristics, such as body conformity, body-heat transfer and vapour permeability are bound to influence the quality of sleep.
The experimental results suggest that at the evaluated experimental conditions the existent limitations on poor oxygen transfer and low permeability when operating a MBR at high MLSS concentrations can be overcome; therefore, the footprint requirements of MBR systems may be further reduced.
There is no matrix fractures transfer because matrix porosity and permeability is very low, or tends to 0%, so that this matrix does not practically contain fluids.
All three models are shown to provide close agreement when adequate spatial and temporal discretization are applied to represent problem geometry, resolve flow fields and capture advective transport in the sands and diffusive transfer with low permeability layers and minimize numerical dispersion.
The simplest model, applied to MRI data by both Larsson et al. [ 13] and Tofts and Kermode [ 14] allows calculation of the transfer constant (Ktrans) that reflects simultaneously perfusion and permeability, and the leakage space (Ve).
Quantitative measurements can be used to analyse perfusion and permeability parameters, such as the volume transfer constant between plasma and the extracellular extravascular space (Ktrans), which correlates with vascular permeability.
The capillary performance of sintered porous wicks, which integrates both capillary pressure and permeability, determines the operation and heat transfer performance of LHP.
The model couples fluid flow, heat transfer, and serpentinisation reactions with the evolution of porosity and permeability in the pipe's interior.
The measured pressure drops for such heat exchangers are then used to give the overall permeability which is linked to the porosity and permeability of each phase as well as the interfacial momentum transfer coefficient between the two phases.
For example, the transfer coefficient, Ktrans, often correlated with angiogenesis, is influenced by both blood flow and permeability; hence, it is difficult to determine whether the change is due to flow or permeability.
