Due to the complexity of the problem, significant simplifications were inevitable in order to obtain a manageable CFD model, which were done based on the understanding of the problem by the modellers plus engineering judgements.
In the first part, the basic aspects of the model, which were developed in previous studies, are described.
It compares the results obtained with this 2D transient model, when the steady state is reached, with those of a 3D stationary model, which were experimentally validated.
Simple scaling laws for the design parameters of plasma wakefield accelerators were obtained using a theoretical model, which were confirmed via particle simulation studies.
In addition to the framework, the current paper discusses additional features of the index such as the cost model and system design model, which were not presented or discussed earlier.
The improved model contains six of the 10 terms in the full-cubic mixture model, which were selected using a different cross-validation procedure than used in the previous paper.
The best values obtained were 14.04% of SEP for the growth rate and 14.84% for the lag estimation by the best ANN model, which were much better than those obtained by the RSM, 35.63% and 39.30%, respectively.
The models were developed from simulation models of monoculture crops; each competing species was represented by its own growth model, which were then linked by additional routines to account for the distribution of resources over competing species.
Two closure models, Toor's hypothesis and the 3E closure model, which were originally developed for one-dimensional turbulent reactors, have been extended to turbulent reacting flows with multidimensional nonhomogeneous concentration fields.
The first approach utilized the tensile constitutive relationship of SFRC in tension derived from SFRC panel test results, and the second approach adopted the direct tension force transfer model, which were applied to the smeared-truss model.
The results shown 11 elements of the model which were: 1) Problem Base, 2) Resources, 3) Collaboration, 4) Coaching, 5) Scaffolding, 6) Science Clinic, 7) Cognitive Tools, 8) Thai Local Wisdom Room, 9) Scientific Thinking Room, 10) Science Laboratory, and 11) Scientific Thinking Practice Room.
