Our latest paper "On the influence of the storage wall thickness on the parasitic near-wall flow and exergy destruction in stratified thermal energy storages" by Hannes Ribitza, Clemens Naumann and Christian Cierpka has recently been published in Experimental Thermal and Fluid Science. In experimental investigations, we observed that parasitic near-wall convective flows become faster and exhibit stronger velocity fluctuations at an increased storage wall thickness. Consequently, the thicker wall leads to enhanced heat transfer from the hot storage fluid layer to the cold one, resulting in faster stratification degradation and increased exergy destruction. The results provide insights into loss mechanisms in stratified thermal energy storages and may support their design and optimization for Carnot batteries investigated in the priority program 2403(https://lnkd.in/e43UwPsE) funded by Deutsche Forschungsgemeinschaft (DFG) - German Research Foundation.
