(author)A 140 l lab scale shell-and-tube PCM heat storage was built and tested, and the experimental results were compared to a numerical model. Natural convection in the PCM was found to significantly influence the local temperature distribution in the storage vessel, which could not be predicted well by the model, since the model assumes only...article 2018

de Boer, R. (author), Smeding, S.F. (author), Energieonderzoek Centrum Nederland (author)Heat is an important energy source for the chemical industry to drive their processes. Waste heat recovery and re-use therefor provides attractive energy saving and cost saving opportunities. However, in batch processes the availability of waste heat and the demand for heat are shifted in time and storage of thermal energy is needed to overcome...conference paper 2017
