A Electronic Control Stirling Engine Fuel Supply System Based on Real-Time Operating System
Advanced Materials Research, 2014Co-Authors: Jian Xin Liu, Dong Wei Chen, Zhan Cheng WangAbstract:The uC_OS-II embedded real-time operation system is used to improve the original designed Fuel Supply system of a Stirling engine which governed by the electronic control system based on a rotating speed control method. Task modules for each level are built and the fail-safe modules are also improved in this paper. The developed Fuel Supply system is investigated through experiment, and test results show that the new real-time operating system works stably and realizes the Fuel Supply fast adjustment.

Research on the Model of Scramjet Fuel Supply System
Applied Mechanics and Materials, 2014Co-Authors: Jin Jiang, Hong Gui ChenAbstract:In order to make a research on the Scramjet Fuel Supply System, I use the software named Flowmaster to make a numerical simulation. In the work, I first make some research on the steady-state response of the Scramjet Fuel Supply System, in which it mainly contains the change trend of the outlet flowrate and the temperature of the working fluid with the variation of the valve's opening, the heating transferred to the fluid and the pressure difference between the inlet and the outlet of the cooling channel. After the simulation of the steady-state characteristics, I make some analysis about the reason casing the Scramjet Fuel Supply System response as this. Then I conduct a calculation of transient process cased the sudden close of the control valve. After the calculation, I also analyze the tendency of pressure changes and the bubble volume generated by the abrupt close of the regulating valve. This may provide some useful theoretical basis and references in the study of characteristics of Scramjet Fuel Supply System.

Gas-liquid two phase transient analysis of scramjet Fuel Supply system
2014 ISFMFE - 6th International Symposium on Fluid Machinery and Fluid Engineering, 2014Co-Authors: Binyuan Wang, Honggui Cheng, Jin JiangAbstract:The Fuel Supply system transports the Fuel oil from the Fuel storage tank to the combustion chamber, and it makes great contributions to ensuring the engine to normally start up, to enter the rated working condition and to shut down without delay as required. The physical model of the Scramjet Fuel Supply System which contains the pressure tank, the turbo pump, the controlling valves, the nozzles and so on is set up in the paper, and the transient behaviors of the pump's starting up as well as the controlling valve's shutting down are calculated based on the characteristic line method. The calculation results show that in the process of starting the pump, the pressure in the Fuel Supply system is greatly affected by the pressure of the oil tank and the time the control valve takes to becoming fully open. While in the course of closing the valve, the valve's closing time and the temperature of the Fuel oil can make profound influences on the pressure and the evaporation degree in the pipeline.

The primary forest Fuel Supply chain: a literature review.
Biomass & Bioenergy, 2013Co-Authors: Ulrich J. Wolfsmayr, Peter RauchAbstract:This paper provides a literature review of articles on the primary forest Fuel Supply chain which have been published in English speaking peer-reviewed journals from 1989 to 2011. The focus is on the key issues of the transportation of primary forest Fuel to heat and/or power plants: (i) transportation modes, (ii) terminal types, and (iii) forest Fuel Supply chain management, and provides basics on the logistically relevant characteristics of wood as feedstock such as on various feedstock assortments. The analysed Supply chains include the transshipment, storage, handling (e.g. chipping) and transportation of primary forest Fuel from the place of harvest to energy conversion plant. Due to spatial distribution, low mass density, low energy density and low bulk density, the transportation of primary forest Fuel is crucial for economic efficiency as well as for reduced CO2 emissions. As a consequence of forests accessibility, road transportation (after hauling the biomass to the forest road) is the first step of the modern primary forest Fuel Supply chain. For longer transportation distances, rail or waterway is preferred because of lower transportation costs per volume transported and lower CO2 emissions. We highlight that some experience exists in multimodal transport, including truck, train or ship. Intermodal transport, however, has not been studied in the past and, therefore, an outlook for the research requirements is made here.

Improving the primary forest Fuel Supply chain.
2013Co-Authors: Peter RauchAbstract:The paper comprises various topics covering the primary forest Fuel Supply chain, provides an overview of actual research and outlines future research issues. Starting with estimating the potential Supply volumes of primary forest Fuel, which proved to be a really crucial task for the whole Supply system, the Supply network is then described. Further development of forest Fuel Supply chain engineering is shown and proven to be a valuable measure in improving Supply chain performance. The paper concludes with critical reflections on some shortcomings of developed forest Fuel Supply models and ends by illustrating future research options.

designing a regional forest Fuel Supply network
Biomass & Bioenergy, 2007Co-Authors: Manfred Gronalt, Peter RauchAbstract:New regulations on bioenergy lead to increasing demand for forest Fuel. This paper describes a new approach to configure a wood biomass Supply network for a certain region, a federal state of Austria. The network consists of several forest areas and a number of energy plants with a total demand of 1.2 million loose cubic meter (lcbm) wood biomass and 502,000 lcbm forest Fuels. Starting with the regionally available forest Fuel and the potential number of heating and energy plants we evaluate the different Supply lines for the woody biomass from forest to plants by calculating the system cost for a number of alternative configurations. Especially, we compare central chipping against a local approach. The main contribution of this paper is to provide an evaluation method of forest Fuel Supply network design for a whole region. r 2007 Elsevier Ltd. All rights reserved.
