为了研究挠性光电互联结构在实际工程应用中的可靠性,建立了埋入光纤挠性基板光电互联结构有限元模型,根据光器件Telcordia GR-468标准加载热循环试验条件,对光电互联结构中的焊点应力、光纤应力和光电耦合效率进行仿真分析。热—结构仿真结果表明,焊点和光纤的最大等效应力均在安全范围内,光电耦合产生的最大损耗为0.7 dB,光电传输未受到显著影响,可以判定挠性光电互联结构在标准热循环作用下能够保证光电传输的稳定性。

Simulation Study of Biomass Gasification [PDF]
生物质气化是生物质利用过程中热效率较高的一种方法,同时也是一种十分重要的可再生能源利用方式。本文采用AspenPlus模拟软件,结合吉布斯自由能最小原理,建立了生物质气化反应器模型,模拟研究了不同操作参数对气化结果的影响,同时对三种气化剂下的气化结果进行了对比分析。 在三种气化剂的模拟结果中,同一操作参数对气化结果的影响有一定共通性:(1)随着气化温度的升高(600~900℃),一氧化碳体积分数升高,二氧化碳和甲烷体积分数降低,但氢气体积分数变化不大;气体的热值升高(700℃以上),气体产率先升高后降低,

The systematic modeling and performance optimization of the integrated solid oxide fuel cell-gas turbine and organic Rankine cycle combined power system [PDF]
中国是世界最大的能源消费国,占全球消费总量的23%,但能源综合利用效率普遍较低。据统计,美国的能源效率高达60%,欧洲超过60%,其它发达国家的平均水平为50%,而中国仅为33%[1]。另一方面,中国单位GDP的能耗是世界平均水平的3.2倍,其中50%以上的工业能耗以热能的形式耗散,温度在350℃以下的低品位余热在工业过程中普遍存在。如何实现能源系统向清洁、低碳、高效的方向转型成为中国当前面临的最大问题之一。 近年来,随着集中式供能弊端的逐渐显露,以燃料电池、有机朗肯循环 ...

Energy Cost Analysis of Heating in Southern China [PDF]
近年来我国南方地区冬季频繁出现冰冻、雪灾现象,2012年我国南方又经历了28年来最冷的冬天,气候条件的改变使各地人大、政协的代表委员开始建言献策,要求南方一些城市开展集中供暖。然而,如何界定南方供暖区域?扩大供暖范围给国家能源供给带来的压力有多大?给国家财政补贴带来的影响有多大?这些问题都是讨论供暖方案首先需要解决的问题。 本文在借鉴前人研究的基础上,创新性地提出估算南方供暖能源消耗成本的方法,对上述问题一一做出了解答。首先,本文通过回顾国内外对不同供暖方式的相关研究 ...

The systematic simulation and performance analysis of biomass gasification fuel cell-gas turbine and ground source heat pump combined cycle [PDF]
生物质气化、地源热泵、燃料电池与燃气轮机联合循环等技术以其清洁、高效、环保等特性,近年来得到国内外众多学者和研究机构的广泛关注。目前针对这几类单项技术的研究已经取得了较多成果,但将这些单项技术进行集成耦合后形成联合循环对其进行系统分析的研究还处于起步阶段,系统的结构、循环的设计、不同单元的规模匹配、部件之间的相互耦合等尚未形成完整的理论体系,需要进行详细的分析和论证。 本文由此提出生物质气化燃料电池-燃气轮机与地源热泵(BGFC-GT-GSHP)的一体化联合循环系统 ...
