However, as the core inlet temperature approaches to 155C at 2. 0 MPa pressure the Ledinegg instability and multichannel oscillation instability will occur in the natural circulation system of the 200 MW nuclear heating reactor.

An experiment has been performed in National Key Laboratory of Bubble Physics and Natural Circulation(BPNC),Nuclear Power Institute of China(NPIC) to study the effect of the main operating parameters and the inlet restriction pressure-drop on the oscillation among channels.
Forced convective air cooling from electronic component arrays in a parallel plate channel
An initial value investigation of the hydromagnetic convection flow of a viscous electrically conducting fluid through a porous medium in a rotating parallel plate channel has been made using boundary‐layer‐type equations.
The effects of viscous dissipation on thermal entrance heat transfer in a parallel plate channel filled with a saturated popous medium, is investigated analytically on the basis of a Darcy model.
Convective heat transfer in a parallel plate channel with porous lining
The paper proposes a theoretical model for the study of flow and heat transfer in a parallel plate channel, one of whose walls is lined with non-erodible porous material, both the walls being kept at constant temperatures.
Three kinds of pathways were found in the plane: parallel pathway, oblique-cross pathway and network pathway.
Conserved fibroblast growth factor response element sites were identified in regulatory regions, suggesting a potential parallel pathway for regulation by FGFs.
Delta-12 (e2) and delta-15 (e3) desaturases are active in the endoplasmic reticulum, while omega-6 (p2) and omega-3 (p3) desaturases catalyze analogous desaturation reactions via a parallel pathway located in plastids.
These findings suggest that facilitatory muscarinic cholinergic neurons may be present either as a parallel pathway in the segmental reflex or longitudinally oriented pathways in the spinal cord.
The mutant phenotype prompted the hypothesis that AMP1 is involved in ethylene and GA signalling pathways or in a parallel pathway-controlling cell and hypocotyl elongation and cellular organization.
