Effect of geometric variations on pressure loss for a model bifurcation of the human lung airway

Abstract Characteristics of pressure loss (Δ P ) 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 r...
