Abstract

Abstract: This paper presents a one-dimensional numerical model of a molten-salt-based thermocline thermal energy storage tank. The model is explained and referenced in detail, allowing for a complete reproduction. It has been successfully validated against experimental and theoretical data from the literature. Unlike previous works, the full boundary conditions of the performed validation simulations are given, enabling future model comparison studies and thus a further check for consistency against other codes. Finally, the model has been optimized regarding simulation speed for CSP performance simulations on system level.
