Thermal conductivity measurement of methanol-based nanofluids with Al2O3 and SiO2 nanoparticles

In this study, the methanol-based nanofluids with Al₂O₃ and SiO₂ nanoparticles are prepared by dispersing nanoparticles in pure methanol using an ultrasonic equipment. The main objective of this paper is to measure the thermal conductivity of the methanol-based nanofluids. We have also measured the zeta potential, particle size and Tyndall effect for the present nanofluids. The transient hot-wire method is applied for measuring the thermal conductivity of methanol-based nanofluids. The measurement uncertainty in repeatability is obtained as 1.95% for deionized (DI) water and 1.34% for pure methanol, respectively. The effective thermal conductivity of methanol-based nanofluids is measured at a temperature of 293.15 K. The results show that the thermal conductivity increases with an increase of the nanoparticle volume fraction, and the enhancement is observed to be 10.74% and 14.29% over the basefluid at the volume fraction of 0.5vol% for Al₂O₃ and SiO₂ nanoparticles, respectively. Clustering of nanoparticles is considered to be the main reason for the thermal conductivity enhancement.

Intergranular Strain Evolution in a Zircaloy-4 Alloy with Basketweave Morphology

A Zircaloy-4 alloy with Widmanst?tten-Basketweave microstructure has been used to study the deformation behavior at the grain level. The evolution of internal strain and bulk texture is investigated using neutron diffraction and conventional microscopic techniques. The macroscopic behavior and intergranular strain development, parallel and perpendicular to the loading direction, were measured in situ during uniaxial tensile loading. It was observed that twinning plays a major role in both microstructural changes and polycrystalline plasticity.

溢流碎流型气液分配器的开发研究

国内在役和设计的加氢反应器内构件多数使用抽吸型气液分配器的分配技术。洛阳石油化工工程公司对抽吸型和溢流型气液分配器的特点进行了技术分析，开发出一种具有碎流板结构的溢流碎流型气液分配器。在主体为直径600mm的有机玻璃塔实验装置上，采用空气和水介质，将溢流碎流型气液分配器与典型的抽吸型气液分配器进行对比实验，结果表明，溢流碎流型气液分配器的压力降比抽吸型的低，对液相的分配均匀性比抽吸型的好，操作弹性比抽吸型的大。
