CONTRIBUTION A L'ETUDE DE LA POLLUTION PARTICULAIRE : RÔLE DES PAROIS, RÔLE DE LA VENTILATION

Abstract : The present study is in line with the indoor air particle pollution and more precisely in the development and the perfecting of modelling tools. The first part starts with a state of art of the indoor particle pollution knowledge. Indoor air particles are listed and classified depending on their origins and sizes. The difficulties of predicting the particle movement are put into relief by the study of numerous elementary forces acting on particles. The second part is dedicated to the development of a indoor concentration prediction model in a monozonal room. Air particles are considered from a global point of view, particle pollution is deduced by identifying interactions between the entire polluted air and the building envelope. An experiment made on a scale model has been designed to study the particle deposition on wall textures. This experimental study permits to quantify the deposition and to elaborate a classification of wall textures versus particle pollution. The last part deals with numerical simulations of particle transport in confined flows such as those encountered in buildings. The development of the LEPTAB particle dispersion numerical model permits to estimate the particle trajectories in the three-dimensional space. Our contribution consists in introducing wall - particle interaction laws to take into account real building textures. These wall laws are based on the results of the experimental study made on a scale model. Perspectives on the development and on the validation of the global model and on the improvement of the particle dispersion numerical code are presented and discussed in the conclusion.
