摘要

本研究分析了在约旦安曼的一家工厂安装的线性菲涅耳反射器（LFR）系统的吸收管内可能发生的两相流。该分析将现有的传热流体水与Therminol VP-1（一种合成导热油）进行了比较，以解决和减轻与两相流地层相关的挑战。使用FluidFlow V3.44软件进行了模拟，以评估系统运营商提供的三种不同操作情况下的温升、输出压力、蒸汽质量以及两相流的可能性。结果表明，模拟结果与水的实际系统行为基本一致。当Therminol VP-1在相同的进口条件下进行分析时，由于消除了两相流的形成，它表现出了优越的热稳定性，并且与水相比，温度分布得到了改善，例如输出温度从水的131.48°C提高到使用Therminol VP-1的138.66°C，提高了LFR系统的整体性能稳定性。这些发现使Therminol VP-1成为一种可行的、有竞争力的替代方案，可以改善LFR系统的热性能和运行可靠性。

Comparative analysis of the heat transfer for a linear Fresnel reflector in Jordan

This study analyzes the potential occurrence of two-phase flow within the absorber tube of a Linear Fresnel Reflector (LFR) system installed at a factory in Amman, Jordan. The analysis compares the existing heat transfer fluid, water, with Therminol VP-1, a synthetic thermal oil, to address and mitigate challenges associated with two-phase flow formation. Using FluidFlow V3.44 software, simulations were conducted to evaluate temperature rise, output pressure, vapor quality, and the likelihood of two-phase flow under three distinct operational cases provided by the system operators. The results demonstrated that the simulations closely align with the actual system behavior for water. When Therminol VP-1 was analyzed under the same inlet conditions, it exhibited superior thermal stability by eliminating two-phase flow formation, and achieved an improved temperature profile compared to water such as the output temperature increased from 131.48 °C using water to 138.66 °C using Therminol VP-1, enhancing the overall performance of the LFR system stability. These findings position Therminol VP-1 as a viable and competitive alternative for improving the thermal performance and operational reliability of LFR systems.

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
