Modeling of a falling film evaporator

Falling film evaporators have demonstrated a good performance in air-conditioning and refrigeration. This paper presents the development of a detailed falling film evaporator model. The model is based on classical Newton’s viscosity law and Nusselt falling film theory. A library of evaporator components compatible with Modelica.Fluid, Modelica.Thermal and Modelica.Media has been implemented. The simulations presented have the expected behaviour. These models will be used to a complete model of a heat
