TubeBundle L1 TML

Created Wednesday 12 June 2013

A model for a fluid flow in a pipe. The balance equations for mass, energy and momentum are implemented in a integral manner, assuming steady flow and linear pressure loss. Energy storage in the surrounding wall is not part of the model. No phase change allowed.

2.2 Physical Effects Considered


2.3 Level of Insight


Heat Transfer

currently a simple heat transfer model is implemented assuming a constant product of heat transfer area and heat transfer coefficient which is given by the user.

Friction Pressure Losses

currently a linear friction loss model is assumed, user-defined by giving nominal values for mass flow rate and pressure difference.
