Second Law analyses of ejector performance have rarely been conducted in literature. Many measures of ejector efficiency have not always been clearly defined and the rationale underlying and justifying current performance metrics is often unclear. One common means of assessing performance is to define a thermodynamically reversible reference process against which real processes may be benchmark...

With the increase in thermal power capacity, ultra supercritical units have become the mainstream of power industry. At the same time, with the improvement of the steam parameters and the lengthening of shafting, the production of steam flow excited vibration is frequent in the ultra supercritical units, which may seriously affect the reliability of the unit. This paper has taken steam flow exc...

The economic feasibility of resource recovery projects depends largely on the amount of revenue that can be obtained from the recovered energy products. The revenue that can be obtained from steam is dependent on the type of steam market available. The type of steam market in turn affects the design of the resource recovery facility and its capital cost. This paper discusses how the proposed st...

This paper presents an effective numerical simulation method for production prediction of in situ recovery oil shale reservoirs with steam injection. In this method, finite volume-based discretization schemes heat and mass transfer equations the thermal compositional model are derived used. The embedded discrete fracture is used to accurately handle fractured vertical well. A smooth non-linear ...

Background: The shortage of skilled workers choosing STEM (Science, Technology, Engineering, and Math) careers in the USA and worldwide has fueled a movement towards STEAM, in which the “A” addresses the arts and humanities. STEAM education has been proposed as a way to offer relevant problems to solve while drawing on creative and collaborative skills to increase interest and engagement in the...

Waste-to-energy approaches, aimed at using cheap energy carriers (oil production and refining waste, etc.), require the creation of new technologies with high efficiency low emissions. One environmentally friendly methods is a superheated steam injection (SIM) into combustion zone. At same time, trends in CO2 reduction recycling make carbon dioxide more attractive to use together with, or inste...

The Extreme Measurement Communications Center at Oak Ridge National Laboratory (ORNL) explores the deployment of a wireless sensor system with a real-time measurement-based energy efficiency optimization framework in the ORNL campus. With particular focus on the 12-mile long steam distribution network in our campus, we propose an integrated system-level approach to optimize the energy delivery ...
