Unsteady turbulent flow in pipelines

This page under construction

This page contains models for unsteady turbulent flow. Publication is pending for this work.

These models may be downloaded for research use. We accept no liability for any problems arising from their use.

All models were created using Matlab R2009b. The models should run without any changes needed; they are set up with typical parameters and some simple boundary conditions.

• Multiple RLC model [last modified 1 April 2010]
• MOC model [last modified 1 April 2010]

The following additional function is needed to run the Simulink models:
