The detailed pyrolysis kinetic model containing 255 species and 960 reactions for n-decane was developed from a classical kinetic model from hydrocarbon combustion (USC Mech Ⅱ) and many paraffins reat
High-order accurate Weighted Essentially Non-oscillatory (WENO) Schemes have recently been developed for finite volume methods in unstructured meshes with the developing of Mesh generation method.In t
分散式风电场能达到小风场发挥大作为,非常具有经济和实用价值。而为确保风电场能够安全、可靠、经济地运行以及实现集中管理监控,开发分散式风电场SCADA 系统致关重要。本文针对分散式风电场SCADA 系统存在的信息集成以及数据传输问题,提出了基于OPC XML 信息集成技术和基于ZigBee 与3G 无线网络相结合的监控系统总体架构。
The distribution of heat flux of the combustor is particularly important for the thermal protection system of scramjet.A new method is presented for calculating the average heat flux through the wall
根据太阳能恒温沼气池的供能性能和我国寒冷地区农民冬季生活用能习惯,构建了一套集成了太阳能恒温沼气池、低温辐射床的30m2 农村建筑,利用CFD 软件模拟了冬季工况下该建筑的室内热环境,并与传统煤炉采暖的30m2 农村建筑进行了对比。研究结果表明:当室外环境温度在253K 时,与传统煤炉采暖的农村建筑相比,太阳能与沼气互补的农村建筑室内温度场分布均匀:竖直方向相邻平面间温差在1K 以下,水平方向房屋
