The distributed response of complex branching duct networks

Abstract

We describe an efficient method for stimulating the distributed response of complex asymmetrically branching networks which satisfy requirements of network self-consistency. Individual tree links may be dispersive and lossy. As a case in point we simulate the response of the human lung, and characterize the variations in pressure with frequency, path, and position. The effects of tree asymmetry are found to be significant above 100 Hz in the air-filled lung.
