In this paper, the effect of various operating parameters, such as primary and secondary fluidizing airflows, on solids circulation within a scaled-down cold model of a circulating fluidized bed (CFB) was investigated.
A three-dimensional model of a circulating fluidized bed gasifier was developed, which uses continuous radial profiles of velocities and solids hold-up with regard to the description of fluid mechanics.
In the present work a particle population balance model for a circulating fluidized bed combustor (CFBC) is developed, that allows the description of the fate of individual particles in terms of attrition and transport effects.
In this work we describe an experimental campaign using static grids to generate turbulence and investigate its impact on a model tidal turbine in a circulating water flume.
This has a large impact on gas and particle modeling and mixing inside a circulating fluidized bed.
Animal models of serum sickness, a circulating immune complex disease, have been shown to develop cellular infiltrates in the uvea [7].
Frequently used flow chambers are characterised by an internal fluid flow along a stationary cell-bearing surface, whereas the osteoblast test cells of this newly developed model are circulating within a resting culture medium.
As shown in a sheep model, unique circulating microRNAs (miRNA) may help identify individuals consuming alcohol and, importantly, those exposed to alcohol in utero.
A mathematical model of circulating IGF-1 (Ac) was developed to include parameters of endogenous synthesis (Ksyn); exogenous uptake (Ka) from the subcutaneous dose (As): and IGF-1 clearance: where dAc/dt=Ksyn − Kout×Ac+Ka×As.
These observations, coupled with the fact that isolated RBCs can take up S1P from media, have led to a proposed model of circulating S1P homoeostasis, in which RBCs buffer this lipid and the binding capacity of plasma components, such as HDL and albumin, regulate the release of the lipid from RBCs.
