Axial Mass Transport by Reciprocating Flow in
Branching Tube Network (Understanding of Gas Exchange Mechanism in Conducting
Airways of Human Lung and Application to High Performance Heat/Mass
Exchangers)
Human lung consists of branching tube network, and
respiration causes oscillating flow with which very efficient gas exchange is
performed. We are studying the axial mass transport phenomena caused by the
oscillating flow in order to understand the mechanism of the phenomena and also
to apply the mechanism to the high performance heat/mass exchangers.
