“…These simulations focused on the design and operating parameters of the system. Zhang et al [14] introduced a device that generates a vortex field from solar energy, similar to the natural dust devils phenomena, that could be used as a sustainable energy source. A small-scale indoor experimental prototype validates their CFD simulation.…”

In this study, a validated computational simulation is presented to investigate the effect of humidity on the performance prediction of the solar vortex engine system. Data from an experimental model are used to validate the CFD simulation. Three humidity cases are considered: dry air, 40% and 80% humid air. An expansion process with heat addition is taking place inside the vortex generator. When the vortex field continues outside the system, a compression process with heat rejection occurs, eventually bringing the air vortex to be thermal and mechanical equilibrium with the surrounding atmosphere. The change in total energy and the heat transfer rate for both processes, inside the vortex generator and outside the vortex generator, increase with increased humidity in the working fluid. The humidity increases the energy required by the system to generate and maintain the air vortex. Compared to the dry air, the pressure drop at the center of the vortex field decreases by (2-5%) and (4-9%) for the 40% and 80% humid air, respectively. Reduced pressure drop decreases the stability of the air vortex when it is in contact with the atmosphere. The intensity of the air vortex is not affected by the increase in humidity.

“…However, it has an inherent low efficiency compared to the other conventional power generator. Much effort have been devoted to improve its efficiency such as adding thermal storage equipment [3,4], studying the influence of geometry to the power production [5,6,7], or modifying the design of the SUPG [8,9,10]. With this reason, we investigate the performance of a solar updraft power generator expected to provide the remote regions in Indonesia with electric power.…”

<p class="TTPAbstract">Solar updraft power generator (SUPG) is a renewable energy facility capable of harnessing the solar energy. The first large prototype of SUPG was built in 1980’s in Manzanares, Spain to evaluate the projected performance of the facility and to serve as verification tools for future power simulator development. In this paper, the performance of a solar updraft power generator is assessed using the developed mathematical model. The model is validated by comparison with experimental data of Manzanares SUPG. The validated model is then used to calculate the amount of energy produced in seven selected locations in Indonesia. The selected cities in Indonesia exhibited a higher average monthly energy production compared to those in Manzanares. In particular a site like Kupang, would generate two times the energy of the Manzanares SUPG. The power production is sufficient for the needs of this isolated area in Indonesia and has the potential to solve the energy issue.</p>

I, your editor, have been visiting Xi'an Jiaotong University since May 2009. I was then appointed Adjunct Professor for five years and ever since, I have been coming to Xi'an every year, the ancient capital of China. Professor Zhaolin Gu, who is the Executive Dean at the School of Human Settlement and Civil Engineering, would like me to take a more active role in the university to provide lectures to the undergraduate and graduate students; to collaborate with the research and to mentor two of his young lecturers at the school, particularly on Atmospheric Pollution, Historical Relics Preservation and Urban and Built Environments. I was later successfully appointed 'Overseas Distinguished Professor' in 2011 for three years funded by the Ministry of Education/State Administration of Foreign Experts in China. This was a great honour, and the university further awarded me the title 'Honorary Professor' in 2012. I was the University's second Overseas Distinguished Professor! The appointment has been renewed and approved in 2015, by the Ministry of Education for another three years, which is another first in the university. I am now becoming very much part of the furniture at Xi'an Jiaotong University, and I have been fascinated and impressed by the subject areas which I have been involved in and contacted with at Xi'an Jiaotong University.The ancient city of Xi'an 1 was the oldest capital of
