Abstract
In this paper a model for compact evaporators and condensers is presented. The
flow along a channel of a compact HE is considered to be 2-D and split into
separated 1-D paths. Then, every 1-D flow path is discretised in as many
elements as required. First, both fluid flow evolution along the heat exchanger
are calculated through the integration of the 1-D conservation equations for
single or two phase flow, assuming that wall temperatures are known. This
calculation is performed through an explicit finite volume scheme, following the
flow path. Once the temperature field for both fluids is calculated, then, the wall
temperatures are obtained from the integration of the wall energy equation
