A Study of Trailing-Edge Losses in Organic Rankine Cycle Turbines

Selection of the optimum prime mover and the working fluid in a regenerative organic rankine cycle

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...

An Alaska case study: Organic Rankine cycle technology

Development of a Low Temperature Geothermal Organic Rankine Cycle Standard

Low temperature geothermal systems are an abundant energy resource in New Zealand with over 260 sites with a resource temperature of 150°C and lower. The Organic Rankine Cycle (ORC) is the standard process for low temperature energy conversion with commercial ORCs utilizing temperatures as low as 90°C, with one site at Chena, Alaska (discussed below) utilizing temperatures as low as 74°C. The a...

a study of baudrillards ideas in brian moores fiction

پیدایش مرحله ی جدیدی از نظام سرمایه داری بعد از جنگ جهانی دوم همزمان است با ظهور عصر اطلاعات و رسانه جمعی. در چنین جامعه ای سیر آزادانه ی نشانه ها در فضای بی اساس مجازی بر سرعت فرسایش واقعیت می افزاید. به اعتقاد بودریار، فقدان واقعیت به واسطه ی شبیه سازی آن و تولید حاد واقعیت (hyperreality) پنهان خواهد ماند. این پژوهش بر آن است که جامعه فرانوین توصیف شده در سه رمان بریان مور را با توجه به نظر...

Adaptive PI Control of an Organic Rankine Cycle Power Plant

In this paper a PI based adaptive control system is developed to control an organic Rankine cycle power plant. In particular, the control of the turbine speed during the transient between the normal operation mode of the system (connected to the grid) and the islandmode (connected to a stand-alone load) is of main concern. A control algorithm suitable for the implementation on a programmable lo...
