In this study, a turboexpander for geothermal energy ORC power system was desgned. R245fa was selected as the working fuild. The factors which influence the performance of the trubine were analyzed and discussed. The software Ansys-CFX is used to perform preliminary steady-state CFD simulations. The...

Opposed-Piston Two-Stroke (OP2S) diesel engines have been successfully used in many applications because of its high power efficiency. Uniform scavenging is used on OP2S diesel engines. Different from conventional diesel engine exchanging systems, intake ports and exhaust ports are located at each sides...

Thin films composed of high pure VO₂ (A) doped W⁶+ ions were successfully prepared by an inorganic sol-gel method. The effects of W⁶+ ions doping on the structure, surface morphology and electrical property the films were investigated. The results show that the solution of W⁶+ ions distorted the lattice...

This paper describes the design of an on-line monitoring system for grid-connected photovoltaic plants. The proposed system consists of a meteorological data collection system for measuring meteorological parameters (e.g. irradiance, ambient air temperature, etc.), a set of data collection boxes for...

With the development of Photovoltaic (PV) power system, the operating quality and generating efficiency have become the major questions that people pay close attention to. PV systems are being installed in various ways and sites with different geographical and climatic condition, such as rooftop, agricultural...

In view of the current shipping industry is facing energy waste, environmental pollution and other issues, energy-saving and emission reduction are imminent. As combined the characteristics of high temperature waste heat produced by marine engine and other equipment on ship with solar thermal system,...

To avoid the fire and explosion danger in the current coking coal moisture control technology, a new coal moisture control technology was proposed in this paper where the superheated steam was used as the drying medium. A self-developed lab scale superheated steam drying experimental setup was constructed...

According to GB/T 19963-2011, taking a mega kilowatt wind power base as an example, study the factors that impacts dynamic reactive power support of wind farms consist of DFIG (Doubly-Fed Induction Generator), such as different types of reactive power compensation devices, performance behavior of wind...

In order to monitor the running status of the PV system at any time, to view the data or the gain, to track the historical data, It's meaningful to develop a data service system from the terminal to the client. The paper analyzes the feasibility of the whole system, and studies the technical problems...
