Evaluation and optimization of melting performance for a latent heat thermal energy storage unit partially filled with porous media
TL;DR: In this paper, the melting performance of phase change materials (PCMs) in a horizontal concentric-tube thermal energy storage (TES) unit was numerically investigated with consideration of natural convection.
Journal ArticleDOI
Comparative and sensitive analysis for parabolic trough solar collectors with a detailed Monte Carlo ray-tracing optical model
TL;DR: In this paper, the numerical results of the comparative and sensitive analysis for different parabolic trough solar collector (PTC) systems under different operating conditions, expected to optimize the PTC system of better comprehensive characteristics and optical performance or to evaluate the accuracy required for future constructions.
Journal ArticleDOI
Melting performance enhancement of phase change material by a limited amount of metal foam: Configurational optimization and economic assessment
TL;DR: In this paper, the melting performance of a LHTES unit with phase change materials (PCMs) locally enhanced by porous media was numerically investigated and the optimal configuration of the porous inserts was obtained after the discussion about the effects of porous geometry and porosity on the velocity and temperature distribution of melting process.
Journal ArticleDOI
A comprehensive model for optical and thermal characterization of a linear Fresnel solar reflector with a trapezoidal cavity receiver
TL;DR: In this article, a comprehensive numerical model was developed by coupling Monte Carlo Ray Tracing (MCRT) and Finite Volume Method (FVM) for simulating the energy conversion process in the linear Fresnel reflector (LFR) with a Trapezoidal Cavity Receiver (TCR).
Journal ArticleDOI
Analysis of thermal stress and fatigue fracture for the solar tower molten salt receiver
TL;DR: In this paper, the authors presented the thermal stress and fatigue fracture of a single tube for the solar tower molten salt receiver, and the critical crack length on outer wall was investigated by using the Crack Tip Opening Displacement (CTOD) method.
