Study on Dynamic Characteristics and Control Strategies of Large Scale Cyclopentane Flooded Organic Rankine Cycle System

Energy Science &Engineering, Volume 14, Issue 1, Page 61-79, January 2026.
Cyclopentane shows great potential as a working fluid for recovering gas turbine exhaust heat in organic rankine cycle (ORC) systems. A dynamic characteristics and control strategies analysis of a flooded ORC system using cyclopentane reveals that system safety can be ensured by adjusting the working fluid pump speed based on evaporator liquid‐level ...

A Recent Review in Performance of Organic Rankine Cycle (ORC)

, 2020
تؤدي زيادة انبعاثات ثاني أكسيد الكربون وأسعار الوقود إلى بذل جهود إضافية في إيجاد حل لتقليل حرارة النفايات البيئية. أحد الحلول الناشئة هو نظام دورة رانكين العضوي (ORC). وهي واحدة من تقنيات استرداد حرارة العادم الواعدة التي تستخدم على نطاق واسع لاستعادة الحرارة المنخفضة إلى المتوسطة بدلاً من نظام دورة رانكين البخاري التقليدي.
