Abstract
Thermocline storage system is considered as a cheaper alternative to the common two-tank molten salt approach. However, its configuration and performance might lead to a catastrophic structural failure known as thermal ratcheting. It may occur when a tank filled with particulate solids is cyclically heated and cooled. This paper aims at studying the transient evolution of thermocline tank wall stresses, taking into account both thermal and mechanical loads. A complete numerical methodology to de...
