Résumé

A numerical model based on the method of characteristics is developed to analyse unsteady flows in laboratory ductwork systems. Damper opening and/or closing initiate time-variable boundary conditions at hood inlets. Minor losses and ductwork friction are included, as well as interaction with fans. Extensive data are obtained from two university laboratory systems for purposes of code versification. Comparisons between experiments and simulations demonstrate the accuracy and versatility of the numerical model.
