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 ...

It is worth noting that the CSTR-PFR model is reduced exactly to the traditional CSTR model when t ≥ H/Ug. For the purpose of non-dimensionalization, letF=CCsatandθ=tτwhereτ=HUg Then, the dimensionless mass balance equation is∂F∂θ=klalτ(1-F)θ,0⩽θ⩽1klalτ(1-F)...

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,...
