Solid sensible heat storage is an attractive option for high-temperature storage applications in terms of investment and maintenance costs.Typical solid thermal energy storage systems use a heat transfer fluid to exchange heat as the fluid flows through a tubular heat exchanger embedded in the solid storage material.The modified lumped capacitance method is used with an effective heat transfer coefficient in a simplified analysis of the heat transfer in solid thermal energy storage systems for a solid cylindrical heat storage unit.The analytical solution was found using the Laplace Transform me-Modified lumped capacitance method;thod.The solution was then used to develop an optimization method for designing solid storage modules which uses thesystem requirements (re-leased energy and fluid outlet temperature) as the constraint conditions and the storage module cost as the objective function for the optimization.Optimized results are then given for many kinds of system configurations.

四川盆地五峰组—龙马溪组沉积了丰富的富有机质页岩. 国际地层委员会将黑色页岩段分为凯迪阶、赫南特阶、鲁丹阶、埃隆阶和特里奇阶5个阶.随着我国南方海相页岩气勘探开发的深入,过去的笼统的五峰组-龙马溪组小层划分方案已经不能指导页岩气水平井靶体位置详细确定,长宁、威远、昭通、涪陵四个地区地层难以进行横向对比.龙马溪组目的层段划分跨越鲁丹阶和埃隆阶,难以与国际地层划分接轨.以测井为主的储层分层在小范围内出

本文通过异质结模拟软件wx-AMPS模拟了结构为Ag/AZO/n-InP/p-Si/p+-Si/Au的InP-Si异质结太阳电池的效率.模拟参数有InP的掺杂浓度、禁带宽度、厚度以及背面场(Back Surface Field,BSF)的掺杂浓度与厚度,前表面复合速率等.模拟结果表明电池效率随着InP掺杂浓度、厚度的增加而降低,InP的带隙大于1.35eV后对电池效率的提升影响很小;BSF层的掺杂

基于有限元模拟(Finite Element Modelling,FEM)分析在不同太阳辐照度情况下光伏系统对屋面温度以及建筑室内温度的影响特征.比较分析覆盖有光伏组件与没有光伏组件的屋面温度和建筑室内温度,结果显示安装有屋面光伏系统的屋面平均温度相对低4.4—8.5K,并直接导致建筑室内温度比普通建筑低1.64～3.14K.光伏组件除了本身发电以外,对附加式光伏建筑具有隔热保温作用,在工程应用中
本文采用溅射后硒化工艺,研究了金属预制层合金化过程对背电极处MoSe2的生长的影响以及对Cu2ZnSnSe4(CZTSe)薄膜电池性能的影响.通过对金属预制层进行300℃的低温合金化处理,能够得到致密的Cu5Sn6合金薄膜.合金化过程结束后,在足量Se气氛中采用快速升温的过程能够得到致密的CZTSe薄膜.致密的合金薄膜和CZTSe薄膜在硒化处理过程中能够延缓Se元素向背电极的扩散,从而抑制背电极表
