Open data for Miniatura 6 grant No. 2022/06/X/ST8/00025

The data set contains open data that constitute the results of the implementation of the grant entitled: Study of the properties of phase change fluids - CFD simulations. The experiment included the construction of a CFD model. The tests carried out were numerically modelled through two methods to simulate heat accumulation by the phase change material used in the exchanger. Method A involved modelling the material filling the exchanger by appropriately modelling its physical parameters, taking into account the heat of the phase transition directly in Ansys Fluent. Method B consisted of creating an external user-defined function (UDF) script to define the temperature change on the cylinder walls in the exchanger, taking into account the heat accumulation by the phase change material.
The data package consists of five files that contain the values ​​assumed in Methods A and B, the values ​​for the assumed boundary conditions, and the results of the heat recovery efficiency and temperature obtained in the CFD simulation.
The results were published in the article Development of a Numerical Simulation Methodology for PCM-Air Heat Exchangers Used in Decentralised Façade Ventilation Units, Energies 2023, 16(15), 5610; https://doi.org/10.3390/en16155610.
