Abstract
Natural gas, the cleanest fossil fuel, is a bridge to renewable energy systems and has received strong attention. There are still some challenges in the production of liquefied natural gas. This article experimentally investigates the condensation friction pressure drop of hydrocarbon mixture fluids during the liquefaction process of natural gas. Analyzed the effects of factors such as vapor quality, mass flux, and operating pressure, observed the flow regimes in the spiral pipe using a visualization system, divided the condensation flow patterns into four types, and obtained conversion criteria. Subsequently, the accuracy of eleven classic prediction models of friction pressure drop was compared, and a global model of friction pressure drop suitable for hydrocarbon mixture fluids was developed, incorporating flow regime-based mode and general mode. The global model had a mean absolute relative deviation of 12.5 % and 17.3 % under flow regime-based mode and general mode, respectively. Compared with the experimental and published paper data, it was verified that over 80 % of the data points had errors within 20 %.
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.
