Abstract We present a strategy for the design of ferromagnetic materials with exceptionally low magnetic hysteresis, quantified by coercivity. In this strategy, we use micromagnetic algorithm that have developed in previous research and which has been validated its success solving “Permalloy Problem”—the well-known difficulty predicting composition 78.5% Ni lowest coercivity Fe–Ni system—and in...

It is now well recognized that we are witnessing a golden age of innovation with novel materials, with discoveries that are important for both basic science and industry. With the development of theory along with computing power, quantum materials design-the synthesis of materials with the desired properties in a controlled way via materials engineering on the atomic scale-is becoming a major c...

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...
