On the Simulation of Respiratory Dynamics
The lung respiration is studied in terms of simulation to look into the dynamic behaviors of the lung. The excised lung consisting of the airway tree and the lung parenchyma subsystems is dealt with under the assumptions of finite elasticity and gas-tissue interaction taking account of the surface tension stress in the constitutive equation of parenchyma. The flow equations of gas-tissue interaction are solved by discretization through adjoint variational principle. The emphasis in the following article will be on the computational aspects of the modeling and the discretization technique.
