PFRMass balance models for elongated lakes have been developed. In these models particular attention is paid to the hydraulic description of the lake and to the description of net sedimentation. The hydraulic description is a linear combination of CSTR and PFR, with a coefficient regulating the ...
Sodium-cooled fast power reactors are being most actively studied in the UK, France and USSR where the following prototypes have been constructed: Dounreay PFR (250 MWe), Marcoule Phenix (250 MWe), and Shevchenko BN-350 (350 MWe). The Dounreay Prototype Fast Reactor (PFR), which achieved ...

The core method underestimated NPPFR because it does not account for simultaneous fine root growth and mortality. Minirhizotron NPPFR estimates ranged from 59 g m(-2) year(-1) for aspen stands at SSA to 235 g m(-2) year(-1) for black spruce at NSA. The ratio of NPPFR to total ...
Mass recycle PFRDissipativityIn this contribution we propose dissipation conditions using the second law of thermodynamics for a class of first order hyperbolic thermodynamic systems. The entropy function is used as a storage function and the internal entropy production as the dissipation function. The ...
A population balance method was used to predict the behaviour of the system, the drops being characterized by three variables鈥攙olume, age (time since last interaction or entry into the vessel) and concentration of the transferring solute. Moment generating functions were used to obtain accurate,...
