| Abstract: | The paper deals with the three dimensional numerical simulation of the reciprocating flow in a branching network, a phenomenon that might be found for example in the human bronchi. As the first approximation, the working fluid was water with laminar flow regime. The main issue was to elucidate the mechanism of the air exchange in the human lungs. The model used in this simulation consists of two branching generations. Three different cases have been analyzed with various frequency, Re and Wo numbers. |
