Commercial steel roofs are an attractive platform for building-integrated photovoltaics (BIPV).The potential advantages include the reduction of labour and materials when contrasted to a building-attached system.This system and electricity cost reduction can be more than 25%,which will make this solar-generated electricity less expensive than grid electricity in all of Australia and many other locations.We are developing a building-integrated photovoltaic (BIPV) roofing material to be factory-integrated with low-cost steel roofs for commercial buildings.This roofing product is based on the ultra-thin silicon on steel (UTSi) solar cell.It is being developed in collaboration with AmberWave Inc.based on epitaxial growth of a thin layer of monocrystalline silicon grown on porous silicon.Efficiencies of up to 16.8% on 4cm2 devices and 15.9% on 88cm2 devices have been demonstrated to date,both with an active layer thickness of just 18 μm.The near-term solar cell efficiency potential of the UTSi solar cell is well above 20%.Details of the solar cell and its value when applied to a steel roof component will be described.

本文建立了等离子体射流的二维/轴对称数学模型,根据CE/SE方法的基本思想,推导了适合于求解二维Euler方程的守恒元与求解元方法,并进行数值模拟,用Matlab绘制了等离子体射流场的图像,分析了等离子体射流场特性。结果表明,等离子体射流场存在着激波、膨胀波等复杂的流动现象,同时表明,CE/SE方法具有很强的捕获强间断的能力。
CE/SE方法是最近才发展起来的计算强间断的最有效的方法之一。本文应用高精度的CE/SE方法模拟了爆点周围有挡波墙的二维粘性爆炸场,具体分析了挡波墙与冲击波相互作用的规律,得到了能够反映波系结构变化的压力等值线图。数值结果显示了冲击波遇挡波墙发生反射、绕流等现象;通过与无挡波墙时爆炸流场对比,分析了挡波墙的削波作用;最后改变挡波的墙高度、厚度,对远场压力变化做了进一步分析。数值模拟结果符合相关物理
