The aim of this project was to create a computer model of a climbing film evaporator using COMSOL Multiphysics. We used the climbing film evaporator lab designed for CHE 4402 to structure our lab experiment and to collect lab data about the change of composition in the evaporator feed solution. The data was then used to create a simulation model using COMSOL Multiphysics. The results of the COMSOL model agreed well with our data in most cases. We concluded that COMSOL can be an effective tool for simulating a climbing film evaporator given the correct heat transfer coefficients, heat flux expressions, boundary conditions, and concentrations and we developed recommendations, which we present regarding future modeling and experimentation.
