چکیده

Two new classes of nodal methods, respectively weakly and strongly discontinuous ones, are introduced and applied to the neutron transport equations in X-Y geometry in the discrete ordinates approximation. These methods are then applied to approximate the solution of a well-known benchmark problem of the nuclear engineering literature. The results obtained are nally compared to the ones obtained by recent classical nodal methods. R esum e : Deux nouvelles classes de m ethodes nodales, faiblement et forte-ment discontinues, sont introduites et appliqu ees aux equations du transport de neutrons en g eom etrie X-Y et en ordonn ees discr etes. Ces m ethodes sont ensuite utilis ees pour l'approximation de la solution d'un probl eme de r ef e-rence bien connu de la lit erature d'ing enierie nucl eaire. Les r esultats obtenus sont nalement compar es a ceux obtenus par des m ethodes nodales classiques r ecentes.

Progress in Nodal Methods for the Solution of the Neutron Diffusion and Transport Equations

-Recent progress in the development of coarse-mesh nodal methods for the numerical solution of the neutron diffusion and transport equations is reviewed. In contrast with earlier nodal simulators, more recent nodal diffusion methods are characterized by the systematic derivation of spatial coupling relationships that are entirely consistent with the multigroup diffusion equation. These relation...

Inverse nodal problem for p-Laplacian with two potential functions

In this study, inverse nodal problem is solved for the p-Laplacian operator with two potential functions. We present some asymptotic formulas which have been proved in [17,18] for the eigenvalues, nodal points and nodal lengths, provided that a potential function is unknown. Then, using the nodal points we reconstruct the potential function and its derivatives. We also introduce a solution of i...

Role of slow pathway after nodal fast pathway ablation on the basic and rate- dependent properties of the isolated rabbit atrioventricularNode

  Introduction : The aim of this study is to obtain new insight into possible relation between functional properties of slow concealed pathway and rate-dependent properties of AV-node.   Methods : Rate-dependent nodal properties of recovery, facilitation, and fatigue were characterized by stimulation protocols in one groups of (N=7) isolated superfused AV-Nodal rabbits. Small miniature lesions ...

Influence of Explant Nodal Positions on the In Vitro Shoot Regeneration of Rose

The influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘Bianca’ and ‘El Torro’. Third, fourth and fifth nodal explants were cultured on the modified MS medium supplemented with 1.0 and 5.0 mg/l BA. In both the cultivars, higher rate of proliferation (‘Bianca’ 3.75; ‘El Torro’ 2.65) were obtained from the explants distal to the a...

A Nodal Expansion Method for Solving the Multigroup Sp3 Equations in the Reactor Code Dyn3d

The core model DYN3D which has been developed for three-dimensional analyses of steady states and transients in thermal reactors with quadratic or hexagonal fuel assemblies is based on nodal methods for the solution of the two-group neutron diffusion equation. Loading cores with higher content of MOX fuel, the increase of the fuel cycle length and new types of reactors are challenging for these...
