MEng Group Project 2010/11

Geometric Modeling of Human Lungs and Gas Flow Simulation

Introduction to Project

Objectives

The aim of this research is to produce a coupled 3D-1D geometric model of the human respiratory system and simulate pulmonary airflow through the conducting airways. This will be achieved through the creation of a geometric model of the airway and associated vessels combining three dimensional data produced by X-ray Computed Tomography radiography with one a dimensional fractal structure used to model bronchial airways from the limits of the data available from radiographic methods to the level of the terminal bronchioles.

Methodologies

This research project consists of four components required to produce an accurate and effective model of the flow in the respiratory system:

  • Geometric modeling of one dimensional fractal structure
  • Composite mesh generation produced from three dimensional CT data and one dimensional fractal structure
  • Three dimensional and one dimensional CFD analysis
  • Budgeting and financial management of research project
