The performance of a PDC depends on the absorption of solar irradiance and heat loss through the receiver. Furthermore, to address the problems of solar intermittency and lack of irradiance after sunset requires thermal energy storage. Consequently, an appropriate design of the receiver is necessary for maximizing the performance of the PDC. This study investigated the incorporation of phase change materials (PCMs) into conical cavity receivers to enhance the thermal energy storage and efficiency of PDCs. To examine this, a comparative experimental analysis was conducted on a PCM-filled conical receiver and a conventional cylindrical receiver under identical operating conditions. The methodology involved measuring key performance metrics, such as the thermal efficiency, exergy efficiency, Nusselt number, and heat transfer coefficients, across varying flow rates of the heat transfer fluid. The results demonstrated that the PCM-integrated conical receiver achieved a 42% increase in the thermal efficiency and a 31% improvement in the exergy efficiency compared to the cylindrical design. The capacity of the conical receiver for intercepting solar radiation and PCM integration contributed to superior heat transfer performance, particularly at higher flow rates, as evidenced by the elevated Nusselt numbers and convection heat transfer coefficients. These findings highlight the potential of PCM-integrated conical receivers for mitigating the challenges of intermittent solar irradiance and enhancing the reliability and sustainability of solar thermal systems.</div></div>","PeriodicalId":100472,"journal":{"name":"Energy Storage and Saving","volume":"4 2","pages":"Pages 166-178"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The uniformity of pressure within the symmetrical working chambers of the scroll compressor significantly affected the work efficiency. This study utilizes computational fluid dynamics simulation technology to investigate methods for improving the uniformity of pressure within the symmetrical working chambers of a scroll compressor. First, the axial clearance on one side was calculated for the first time. The results indicate that when the axial clearance was located at the top of the orbiting scroll, the maximum pressure difference in the symmetrical working chambers decreased from 1.21 MPa to 0.83 MPa. Second, the groove at the beginning of the orbiting scroll can significantly enhance pressure uniformity. Under the calculation model provided in this paper, the average power of the scroll compressor can be reduced by 232.58 W, a reduction of 17.39%, through the groove. Finally, this study presents matching principles for the design of the groove and exhaust ports to ensure that both working chambers are simultaneously connected to the exhaust port. When the diameter of the exhaust port was reduced, and the size of the exhaust port did not match the groove, under the low-pressure-ratio working condition, the maximum pressure difference of the compressor increased by 0.20 MPa, and the average power increased by 158.95 W.

The most common method for accumulating solar energy is the use of solar collectors. Based on the accumulation method, solar collectors can be divided into focused and concentrated. Parabolic trough collectors (PTCs) are a of concentrating solar collector in which a solar beam is reflected by a parabolic reflector and accumulates at the outer surface of the absorber tube. The fluid flowing through the inner surface of the tube carries heat and either stores it or uses it for different purposes, such as cooking, industrial heating, and room heating.

RESs require interfaces to regulate the power generation. Maximum power point tracking (MPPT) is a technique employed in solar photovoltaic (PV) systems to modify operational parameters to ensureoptimal extraction of power from solar panels. MPPT operates under fluctuating conditions such as sunlight intensity and temperature. An inverter is a device that transforms a direct current into a sinusoidal alternating current. A multilevel inverter (MLI) can be utilized for RESs in two distinct modes: power-generating mode (stand-alone mode) and compensator mode (STATCOM).

The good performance of the proposed model in reproducing the data indicates the validity of the constructed kinetic mechanism for PODE<sub>2–3</sub>. A general framework for PODE reaction pathways was proposed, with special attention paid to the reaction kinetics of each original reaction. Three source routes of PODE reactivity were elucidated: (1) Route 1: a typical chain branching reaction after hydrogen abstraction from the primary carbon, followed by two oxygenation reactions; (2) Route 2: chain branching reactions in the decomposition of partial hydroperoxyl fuel radicals to carbonyl hydroperoxides; and (3) Route 3: chain branching reactions followed by hydrogen abstraction from secondary carbon, leading to low-polymerization fuel radicals. Routes 1 and 2 are chain-branching reaction pathways common to all PODE molecules; Route 3 is a reaction pathway exclusive to highly polymerized PODE, where low-polymerization fuel radicals in the decomposition products enhance the reactivity by continuing to react with oxygen.
