Abstract
Characteristics of pressure loss (ÎP) in human lung airways were numerically investigated using a realistic model bifurcation. Flow equations were numerically solved for the steady inspiratory condition with the tube length, the branching angle and flow velocity being varied over a wide range. In general, the ÎP coefficient K showed a power-law dependence on Reynolds number (Re) and length-to-diameter ratio with a different exponent for Reâ¥100 than for Re<100. The effect of different branching angles on pressure loss was very weak in the smooth-branching airways.
