Daniel mentioned that the first project milestone is due on Tuesday (25/10/11)

For this we need to:

Come up with a project title:

Multi-scale Modelling and Analysis of the Pulmonary Airways

Define Objectives:

Analysing the flow characteristics of the provided 3D model in star-ccm+

Develop a 1D model from the average healthy human lung based on:

The Weibel model

Steady state Bernoulli equations

Experimental data

Combine the 1D model with 3D model to form a multi-scale model of the lung airways

Analyse the entire lung airway model in STAR-CCM+

---

Tom’s view of how it will work in Matlab:

Get STL file put it into STAR-CCM+

Export it to matlab and add the smaller generations

Put the updated model back into STAR-CCM+

---

Charlie suggested the Volume filling method for adding the smaller generations

The reason for this being that realistic airway models are driven by a volumetric efficiency factor

---

The first thing Dr. Chung wants us to do is create a 1D excel file to find Reynolds numbers to aid CFD analysis

---

Tom says that we can import and export to and from Matlab

---

Adrian has made progress with importing the STL file:

Apparently the STL file of the first few generations is setup as just one boundary

He tried to mesh the model, and the software came up with an error message:

It said that there was a hole in the mesh.

---

Dr. Chung said that we need to refine the mesh locally, Adrian is still trying researching how to do this.

---

The group decided to get the first Milestone sheet filled out immediately after the meeting

---

The group decided to make a start on the 1D excel spreadsheet and importing the 3D geometry to STAR-CCM+.
