with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...
Since ordinary gas turbine cycles in actual condition comprise simple cycle, regenerative cycle, reheat cycle and intercooler cycle between high pressure and low pressure compressors, these cycles include 16 combined cycles by combining with a Rankine cycle that consists of three organic fluids and steam. In the present work, the thermodynamic analysis of the above combined cycles with three or...
in this paper, the amount of wasted heat from different parts of a 12 liter compression ignition engine and their potential for waste heat recovery were investigated. then, two-stage configuration of organic rankine cycle was introduced for simultaneous heat recovery from exhaust gases and coolant. finally, parameters like hybrid generated power, engine thermal efficiency and brake specific fue...
Energy shortage is one of the fundamental challenges of human beings in which finding a new way for optimum utilization of unique energy resources and cogeneration can be terminated to the reservation of energy or cogeneration purposes. In this paper, by using the combined Ejector Refrigeration Cycle (ERC) and Organic Rankine Cycle (ORC), in addition to producing power from Organic Rankine Cycl...
clinical differential diagnosisthe organic acidemias are important in the differential diagnosis of metabolic and neurologic derangement in the neonate and of new-onset neurologic signs in the older child. a-organic aciduriaseveral disorders, not classified as primary disorders of organic acid metabolism, have a characteristic urinary organic acid profile that suggests the appropriate diagnosis...
this work investigates the effect of the application rate and type of sludge throughout the soilcarbon cycle in a semiarid mediterranean agro-ecosystem. we study the two-year evolution of the variouspools of soil organic and inorganic carbon and their influence on soil respiration. we applied three rates (40, 80 and 160 mg/ha) of two types of sludge –aerobically and anaerobically digested sewag...

The energy crisis in recent years has led to the use of thermodynamic cycles that work based on renewable energies. Low-temperature cycles—such as organic cycles—are suitable strategies for the application of renewable energies. The present study proposes a novel cycle through the integration of a two-stage compression refrigeration cycle with a combined Rankine power and ejector refrigerat...
مهندسان در طراحی های بزرگ و پیچیده، قبل از ساخت نمونه فیزیکی و برآورد هزینه و زمان ساخت آن احتیاج به شبیه سازی کامپیوتری سخت افزار دارند. از طرفی سرعت شبیه سازهای متداول برای حجم بزرگ مدار بسیار کند می شود و این به دلیل محاسبات زیادی است که برای بدست آوردن اطلاعات ریز زمانی مدار انجام می شود. اما در بسیاری از موارد یک طراح احتیاج به دیدن درستی عملکرد طرح خود دارد و نه اطلاعات ریز زمانی آن. در ا...
