Abstract
This work examines the stability and the density, dynamic viscosity, specific heat capacity and thermal conductivity of a series of polydimethylsiloxane-based nanofluids with TiO2 nanoparticles. Even though polydimethylsiloxane (silicone) is a promising heat transfer fluid for concentrating solar power, its non-polar, aprotic nature complicates the production of stable nanofluids without surfactants or pH control. This, in turn, limits the efficiency and lifespan of these nanofluids. The case study dedicates some space for reflection about the stability challenge for the research community working on nanofluids at fundamental and applied levels. A robust experimental protocol is sketched for quality control in the design of nanofluids, stressing the need for a quantitative assessment of stability before thermal performance is appraised.
期刊介绍：
Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
