Resumen

This paper evaluates a new methodology for calibration of hydrodynamicmodels based on the theory of statistical design of experiments. An Eulerian-Eulerianhydrodynamic homogeneous model, integrated by the commercial software CFX AnsysInc., is used to perform the numerical experiments. For the screening step, the fractionalfactorial experimental design 27-2 was used, followed by a Draper-Lin design of second orderto find the optimum point in the calibration. A new method is introduced to generate thelevel of points to the center and to carry out the test of lack of fit. In this work, we develop avalidated methodology for the calibration of deterministic hydrodynamic models with severalfactors, suggesting a second-order regression model for forecasting the optimum point ofthe simulations, with acceptable accuracy in predicting the response variable.
