The traditional dish type Stirling power generation system cannot match the heat storage system, so is discontinuity. direct steam solar thermal combines latent and sensible energy expected to solve this problem. Currently, research on Graded systems limited single-factor analysis, there have been no reports single-objective optimization cost analysis for such systems. A graded combining in which salt (60% NaNO3-40% KNO3) used as medium, sodium nitrate selected phase change material (PCM),...
Pipeline is a major way for natural gas transportation. Accidental release from pipeline might lead to great economic losses and casualties. Therefore, it important investigate the dispersion characteristics of pipelines. Most previous studies on accidental pipelines mainly focused bare adopted simplified 2D models. This paper first established models buried with high low pressure, respectively. The numerical methods were validated by Trial 26 Thorney Island field experiment model was found...

Abstract Stratified thermal energy storage (TES) tanks are widely used in power plants to enhance the electric peak load shifting capability and integrate high renewable shares. In this study, a data‐driven surrogate modeling optimization study of unequal diameter radial diffuser previously proposed by present authors is conducted. First, based on orthogonal experimental design, numerical experiments performed generate performance database. Then, database establish model via support vector...
Abstract A two‐dimensional model of the charging process on a heat storage unit in shell‐and‐tube type latent subsystem solar power plant with direct steam generation was constructed this study. The effects outer diameter to inner ratio, aspect phase change material (PCM) thermal conductivity, and transfer fluid (HTF) mass flow rate were investigated. Results show that increasing PCM HTF rate, ratio can shorten time, but has an optimal value 6 problem. Using response surface methodology...
The traditional dish type Stirling power generation system cannot match the heat storage system, so is discontinuity. A graded thermal combining latent and sensible in which solar salt (60% NaNO 3 -40% KNO ) used as medium, sodium nitrate selected phase change material (PCM), studied present work. In this through adjusting mass flow of at inlet outlet intermediate tank, curve temperature-enthalpy characteristic water can be more matched. To improve performance paper studies influence law...
A single sensible thermal storage system has the disadvantage of poor efficiency, and a sensible-latent graded can effectively solve this problem. Moreover, virtue being adjustable, which be adapted to many power generation systems. Therefore, paper first analyzes influence factors system’s exergy efficiency. Subsequently, each factor’s significance was analyzed using response surface method, prediction model for efficiency cost established support vector machine method. Finally,...
