Résumé :
|
In the first part of the study, we compare two methods of determining the domain of uncertainty: the quasi-Monte Carlo (QMC) method, and the finite-differences differential analysis (FDDA) method. This comparison is based on the two-dimensional modeling of laminar airflow in natural convection in a small, thermally driven enclosure. The FDDA method is shown to be much more economical, in terms of computing time, than the QMC method.
