“…The slag basicity (CaO/SiO 2 (mass) (C/S)) has a significant impact on the corrosion behavior at the slag–refractory interface 26 . Moreover, various quasi‐volcanic corrosion patterns at the triple‐phase interface corroded by slag with different basicity properties were observed in our previous study; hence, the slag series was prepared according to different C/S ratios but with the same Al 2 O 3 content.…”

A novel phenomenon of quasi‐volcanic corrosion at refractory–slag–air interface under simulated normal smelting conditions was discovered when alumina refractory came in contact with CaO‐Al2O3‐SiO2 slags and soaked at 1600°C. Based on thermodynamic and microstructure analysis, the mechanism of quasi‐volcanic corrosion was revealed and the effect of CaO/SiO2 mass ratio (C/S ratio) on corrosion was discussed. The results indicate that a two‐stage intensified convection led to the severe upwelling corrosion of the refractory at the triple‐phase interface. Furthermore, the critical intensity of the corrosive convection at the first stage on the formation of “slag volcano” was determined. This can serve as guidance for prolonging the service life of alumina refractory.

“…The Mohs' scale of some materials are listed in Table 1 to give an idea about their hardness levels since the resistance to erosion is proportional to their bulk hardness for annealed pure metals [98]. It is interesting to note that these phenomena are interrelated [102,103]. Erosion can trigger corrosion by removing the passive protective layer on a material's surface, especially on metals.…”

Experiments on Single-Phase Nanofluid Heat Transfer Mechanisms in Microchannel Heat Sinks: A Review

For more than 20 years, the use of nanofluids to enhance heat transfer in microchannel heat sinks (MCHSs) has been the subject of a large number of scientific articles. Despite the great potentialities reported in several works, the presence of controversial results and the lack of understanding of heat transfer enhancement mechanisms prevent further advancement in the use of nanofluids as coolants. This article reviews the scientific literature focused on several aspects of nanofluids that have a role in the heat transfer enhancement within the MCHSs: nanofluid stability, thermal conductivity, and particle clustering, as well as the particle–surface interactions, i.e., abrasion, erosion, and corrosion. We also include the most relevant works on the convective heat transfer and MCHSs operated with nanofluids in our review.

“…An interesting example is coffee colloids, which are widely available, inexpensive and eco-friendly. Moreover, they function without other drawbacks inherent to metallic nanofluids such as potential erosion 14 – 16 or nanoparticle deposition/clogging. Nevertheless, this topic has only been discussed in a few papers 11 , 17 , 18 .…”

The paper is devoted to the topic of direct absorption solar collectors (DASCs). Various kinds of fluids can be used as heat transfer fluid in DASCs, and the main focus of our paper is on comparing nanofluids (water with carbon black nanoparticles, concentrations between 0.25 and 1.00% weight) and biodegradable coffee colloids. At first, these fluids were tested by exposing them to irradiation caused by artificial light in indoor experiments, and the corresponding temperature increase was recorded. The fluids were placed in a beaker with a relatively large size so that most of the fluid was not directly irradiated. In these experiments, the performance of the two studied fluids was similar: the resulting temperature increase varied between 46 and 50 °C. Our next experiments involved a smaller system subjected to irradiation obtained by using a solar collector. As a result, we detected an intense absorption on the nanoparticle surface so that the temperature rise in the nanofluid was higher than in the coffee colloids. Next, the process was analysed using a theoretical analysis that gave good correspondence with the experiments. Finally, we extended the theoretical analysis to a DASC with a flowing fluid. The model was validated against results from the literature, but it also supported our experimental findings.
