In 2018, nuclear energy generated 55% of United States’ and one third the world’s carbon free electricity, making a key tool in efforts to mitigate climate change before 2050. However, current technology, light water reactors (LWRs), is limited 300°C, so it cannot be used decarbonize industrial process heat which accounts for 12% US greenhouse gas emissions. High temperature (HTGRs) can meet hi...
چکیده کوه آصف در شمال شهر شیراز قرار داشته که بخشی از جنوبباختری زاگرس چینخورده است. ناحیهی زاگرس چینخورده یکی از مناطق فعال زمین ساختی ایران به شمار میآید. در این منطقه سازندهای سنوزوئیک بر اثر فرایندهای تکتونیکی دچار چینخوردگی شدهاند. نتایج بررسیها نشان میدهد که سطح محوری چینخوردگیها در این منطقه دارای روند غالب شمالباختر- جنوب خاور میباشد، یعنی از روند عمومی زاگرس تبعیت میکن...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
Multi-walled carbon nanotubes (CNTs) are synthesized with the assistance of water vapor in a horizontal reactor using methane over Co-Mo/MgO catalyst through chemical vapor deposition method. The application of Adaptive Neuro-Fuzzy Inference System (ANFIS) technique for modeling the effect of important parameters (i.e. temperature, reaction time and amount of H2O vapor) on the qualit...

Chemical Vapor Deposition (CVD) is one of the most important methods for producing Carbon Nanotubes (CNTs). In this research, a numerical model, based on finite volume method, is investigated. The applied method solves the conservation of mass, momentum, energy and species transport equations with aid of ideal gas law. Using this model, the growth rate and thickness uniformity of produced CNTs,...

Proper orthogonal decomposition (which is also known as the Karhunen Lo eve decomposition) is a reduction method that is used to obtain low dimensional dynamic models of distributed parameter systems. Roughly speaking, proper orthogonal decomposition (POD) is an optimal technique of nding a basis which spans an ensemble of data, collected from an experiment or a numerical simulation of a dynami...
