Analytical analysis of latent heat thermal energy storage model for solar thermal power plants

摘要

In this paper latent heat thermal energy storage system was studied using analytical method for solar thermal power plant applications. The working fluid circulating in circular tube by forced convection charges and discharge phase change material based on energy storage unit. Temperature distribution and parametric study was performed in order to study the effects of convection on the melting/solidification of KNO3 and NaNO3 salts. In order to provide the guidelines for system analysis and design optimization, temperature distribution along the axial and radial direction has been obtained and represented in 3d graphs.
