同理我们可以获得PFR的反应器体积对应的图像 Figure 9: Graphic Area of PFR 不难发现,对于任意一个反应速率和浓度成正相关的反应,(即反应级数大于0),CSTR的反应器体积是出口点+入口点和横轴纵轴构成的矩形,而PFR的反应器体积仅仅为该点之前的线下面积,在这种递增的图线下,出口点的线下面积总是小于这两点张成的...
In each iteration of the message-passing layer, the atomic representations underwent a transformation as described by Equation (1). $${{{\bf{h}}}_{i}^{l+1}=\phi \left({{{\bf{h}}}_{i}^{l},{\sum}_{j\in {{{\mathcal{N}}}(i)}\psi \left({{{\bf{h}}}_{i}^{l},{{...
They have, however, assumed first order kinetics for biodegradation and consequently, could obtain an analytical solution to the performance equation. This, by itself, forms the serious limitation of their work and the results reported can be applied only to those specific cases where first order ...

results on the multi-product reactor network.For dynamic optimization, simultaneous collocation strategy is applied to discretize the continuous time/volume horizon into finite element mesh and to covert the differential-algebraic equation (DAE) optimization problems into nonlinear programming problems (NLP)...
On the upshot, FEA breaks the initial problem into manageable bits known as finite elements and then assembles the basic equations that describe each element into a more sophisticated equation that would explain the entire problem. As a consequence, FEA may interpolate a set of points using ...
This paper offers a nonlinear controller for a non-isothermal PFR governed by time-delay first-order partial differential equation (PDE). Due to, an Extended state-dependent differential Riccati equation (ESDDRE) of the PFR system, a sub-optimal nonlinear controller is suggested. At the first ...
The equation implies that a conductivity becomes nil if there no flux along the edge. The conductivity increases with the flux. The f is monotonically increasing continuous function satisfying f(0) = 0. Then the network Poisson equation for the pressure can be obtained from the Eq. (...
