determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. in this paper, the maximum power of the mgt-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. in a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...

پایان نامه :وزارت علوم، تحقیقات و فناوری - دانشگاه صنعتی خواجه نصیرالدین طوسی - دانشکده مهندسی مکانیک 1381

در این پایان نامه در ابتدا دلایل شکل گیری آلاینده ها در شرایط cold start و warm up و راهکارهای کاهش آنها ارائه می شود. در ادامه، بهینه سازی فرایند شکل گیری مخلوط هوا و سوخت از طریق کنترل دقیق نسبت هوا به سوخت بعنوان یکی از بهترین راهکارهای عملی کاهش آلاینده ها در شرایط cold start و warm up با جزئیات کامل مورد بررسی قرار می گیرد. مدل بدست آمده (برای موتور پیکان انژکتور)، شبیه سازی می شود و نتایج...
