TU Wien Academic Press - New release: Kasper: Modeling of the phase change material of a hybrid storage using the finite element method

Lukas Kasper: "Modeling of the phase change material of a hybrid storage using the finite element method"

New research results from the Institute of Energy Systems and Thermodynamics: In this diploma thesis, a two-dimensional model using the finite element method is developed to simulate the PCM of the hybrid storage as designed in the HyStEPs project. The apparent heat capacity method is applied in a MATLAB implementation, considering heat transfer by both conduction and natural convection. This successfully validated code can handle any desired layout of materials arranged on a rectangular domain.

Furthermore, a parameter study of different dimensions and orientations of the PCM cavity was conducted. The impact of natural convection was found to lead to significantly varying behaviour of the studied cavities with different orientation during the charging process, while it was found to be negligible during the discharging process.
