摘要：

The present study presents a theoretical model for the performance of a shell and tube latent thermal energy storage (LTES) unit using multiple phase change materials (PCMs). The model is based on the enthalpy method. Numerical simulations are carried out to investigate the effects of different multiple PCMs on the melted fraction, stored thermal energy and fluid outlet temperature of the LTES unit. Numerical results indicate that PCMs' fractions and melting temperatures play an important role in the performance of the LTES unit. As a result, appropriate choosing of multiple PCMs is very significant for the performance improvement of the LTES unit. (c) 2006 Elsevier Ltd. All rights reserved.
