Study on Flow Behavior in Terminal Bronchus of Human Lung for Porous Medium

Abstract

Flow simulation along human lung channel is one of the interests of investigation in fluid dynamics. We have studied flow phenomena of 11th generation of human lung as porous medium. The governing equations of porous medium have been solved numerically using finite difference scheme. The effect of different flow parameters are illustrated graphically. It is observed that the flow rate increases for increasing the value of pressure gradient, the porosity effect, effective viscosity and the dimensionless parameter . The numerical experiment for non-porous medium is also studied. It is found that the flow rate increases in porous medium compared with non-porous medium. GANIT J. Bangladesh Math.

Simulation of Air Flow along Human Lung for Cylindrical Channel of Porous Medium

“…For non-porous medium we take 0 ϕ = in Equation ( 3), Equation ( 4) and Equation (5). Then the axial momentum equation reduces to…”

“…In that work, the flow convection in lower airways were investigated and obtained physical perception of old air deportation. Flow behavior in 11 th generation of human lung through square duct of porous medium has been investigated [5]. On that work flow rate was shown for different parametric effect as pressure gradient, porosity, permeability and viscosity.…”
