IdealShell L2

Created Monday 08 April 2013

A simple heater/cooler model with ideally stirred phases at the shell side and a heat port for transferring a heat flow. The tube bundle side is not modelled.

1. Purpose of Model



The model is able to transfer a heat flow from/to a fluid via a heat port without modelling the tube side. The geometry definition considers the volume of a tube bundle inside the shell side, though. The model can be used, whether if a known heat flow is transferred to a fluid via a heat exchanger or if a heat flow is transferred from a defined temperature boundary.

2. Level of Detail, Physical Effects Considered and Physical Insight


2.1 Level of Detail

Referring to Brunnemann et al. [1], this model refers to the level of detail L2 because the system is ideally stirred at the shell side.

7. Remarks for Usage

These models calculate the heat transfer on the basis of the geometry and the actual media properties. However, since the model will usually be attached to a heat flow boundary it is strongly recommended to stick to simple heat transfer models as the heat flow is defined by the boundary in this case.
