✦ Synopsis

Transport by diffusion and convection is described in a branching tube using a stochastic formulation in a multiple pattern network. The concentration curves are compared with the solutions of the classical one-dimensional transport equation for each branch, coupled with a constraint condition at the branch point. A very good agreement is found for a large domain of variation of the parameters compatible with the lung anatomy. The present analysis gives a sound basis to the multibranch point models of the lung. * The author is indebted to Miss C. Delporte, Mr. A. Van Muylem, and Mr. P.
