Past Computational Fluid Dynamics(CFD) work on the Rapidorr 444 required a quantitative check of its accuracy. Factory tracer tests were used to validate the developed CFD model. Since the model was a function of its input, these parameters, particularly juice and mud densities were re-calculated over an entire season and average values used. In addition a new three-dimensional model of the Rap...

Typical model reduction methods for parametric partial differential equations construct a linear space V n which approximates well the solution manifold M consisting of all solutions u ( y ) with vector parameters. In many problems numerical computation, nonlinear such as adaptive approximation, -term and certain tree-based may provide improved efficiency over methods. Nonlinear replace by Σ . ...
