In this paper, a new design of inclined solar still with steppe absorber plate, slope surfaces and baffles were proposed, fabricated, tested modeled using ANSYS FLUENT software, in order to develop the simple cheapest type desalination. The simulation has been carried out validated experimental data for climate conditions Rabat-Morocco (34°47’N) obtained from our existing prototype. It found th...

Generation of terahertz (THz) radiation has been a hot research topic in recent years. Plasmonic quantum cascade lasers (QCLs) are among the most compact and efficient sources to generate THz radiation. In this paper, we comprehensively study plasmonic QCLs designed based on antenna-feedback structure about center frequency 3 THz. By changing geometric cavity using two-dimensional simulation, m...

Abstract We obtained well-sampled optical photometry of GRB 110213A, including Swift/UVOT and XRT. Combining our data from those other ground-based telescopes, we present 15 multicolor light curves showing similar shapes with two peaks. In contrast, in the X-ray band, only a single peak is observed between Temporal spectral analysis 110213A shows that X-rays differ for Phases I–III (before seco...

in this paper, considering the importance of incoming flow turbulence intensity into combustion chamber, tripping wire effect on the flow wake has been experimentally investigated within a linear compressor cascade. to do this, two wires were implemented along each blade and their effects on average velocity, turbulence intensity and vortices frequencies at reynolds number 45500 were accurately...

iran’s vast common natural gas resources and the necessity to extract and export it as liquefied natural gas (lng) to distances more than 3000km opens a lucrative field for researchers to optimize lng cycles. in this article heat integration in cryogenic cycles by determining interacycle partition temperature and optimizing refrigeration features like subcooler, presaturator, aftercooler, reboi...
