در این رساله عملکرد یک موتور توربوپراپ که ملخ آن از نوع clark y 5868-r9 است در شرایط نقطه طرح (on- design) و خارج از نقطه طرح (off- design) مورد مطالعه قرار گرفته شده است. موتور توربوپراپ یکی از انواع موتور جت در تراست بالا و مصرف مخصوص سوخت پایین است که عدد ماخ پروازی آن هرگز از 8/. تجاوز نمی کند. دور موتور های توربوجت به حدی زیاداست که در صورت اتصال مستقیم به ملخ، سرعت نوک تیغه های ملخ به سرع...
Electric vehicles (EVs) are considered as a ground-breaking innovation for making transportation services more sustainable. Electric vehicle batteries (EVBs) are the major technological components of electric vehicles and account for up to one third of the EVs’ initial price. Due to continued cell degradation, EVBs need to be removed from the EVs after some time, but might still be reused in di...
In this research, a thermodynamic model used to describe the growth of single crystals by chemical vapor transport technique with iodine as the transporting agent. The optimum growth condition in the system has been predicted theoretically based on partial of different components. Some experiments were carried out for growing crystals by the chemical vapor transport method using iodine as a ...
Patients in a forensic psychiatric facility often require escorted transport to medical facilities for investigations or treatments of physical health ailments. Transporting these patients presents significant safety and custody challenges because of the nature of patients housed in forensic psychiatric facilities. A significant proportion of these patients may be transfers from the Department ...
Y ou could be forgiven for thinking you had misheard her at first: “I always found polymers to be a bit suspicious,” says Tanja Weil, who completed her doctorate at the Max Planck Institute for Polymer Research and is now Director there. Polymers are long, often net-like molecules composed of numerous small chemical subunits that are repeated many times. The highly versatile and durable synthet...
Organic solar cells (OSCs) have shown great promise as low-cost photovoltaic devices for solar energy conversion over the past decade. Interfacial engineering provides a powerful strategy to enhance efficiency and stability of OSCs. With the rapid advances of interface layer materials and active layer materials, power conversion efficiencies (PCEs) of both single-junction and tandem OSCs have e...
