The JARA2i model of the heat exchanger is based on the physical model described in (Cutlip and Shacham 1999). A gaseous mixture of carbon dioxide and sulfur dioxide (in the tube) is cooled by water (in the shell). The JARA2i model allows two modes of operation: cocurrent and countercurrent flow. The temperature dependence with the spatial coordinate has been modeled by dividing the flow paths of the water and the gas, and the pipe wall in control volumes. This approach allows for local variations in physical properties and heat transfer coefficients.
