Semi-transparent perovskite solar cells(ST-PSCs)have attracted great attention not only owing to the numerous optoelectronic merits of metal halide perovskites,but also their extensive applications for building-integrated photovoltaics and tandem solar cells[1].For practical commercialization,it is essential to transfer the decent photovoltaic performance of small-area ST-PSCs into large-area perovskite solar modules(PSMs).

基于叶素动量理论、升力线及面元法等的涵道螺旋桨桨叶设计方法,由于方法本身存在诸多简化,故设计结果一般同真实性能存在一定偏差。而基于更为准确的CFD求解方法所进行的设计及优化设计等,由于需进行大量CFD计算,设计效率偏低。因此,为使设计具备快速性的同时也具备较高的准确性,基于叶素动量理论,通过CFD计算对设计进行修正,提出一种涵道螺旋桨桨叶高效设计方法。在设计过程中通过对入流角及迎角进行修正,提高了设计的精度,而修正系数通过CFD结果反解得到。初步设计后,经过修正系数求解、再设计进行迭代,可快速得到满足设计需求的涵道螺旋桨。对不同状态涵道螺旋桨的设计表明,该设计方法基本进行2次CFD计算与再设计便可满足设计要求,设计高效的同时具有较好的设计精度。

基于叶素动量理论的对转涵道风扇桨叶设计方法虽然设计速度快,但设计精度不高。为提高设计方法的设计精度,同时保留设计的快速性,通过CFD计算对基于叶素动量理论的桨叶快速设计方法进行修正,提出一种耦合CFD修正的对转涵道风扇桨叶高效设计方法。通过CFD计算与修正设计的不断迭代,可使设计结果收敛至CFD计算结果,得到满足设计要求的桨叶。结果表明:MRF方法对对转涵风扇性能的求解精度不足,需采用非定常CFD方法。而通过CFD计算结果修正桨叶的拉力占比、入流角及叶素气动力后,对转涵道风扇总拉力设计精度提高10.4%,扭矩设计精度提高18.2%。文中提出的高效设计方法只需进行少量的CFD计算修正便能较好地满足设计要求,进行加速处理后,设计效率进一步提高25%。

对于含有多个旋转动力单元的流场的求解,其模拟的高效与准确性是研究相关气动布局的关键。而采用动力单元真实模型进行数值模拟的方法,均面临求解效率不高的问题。因此,以旋翼悬停状态为例,首先以薄体网格圆盘代替真实桨叶,建立了高效求解的定常动量源法。接着,在定常动量源法基础上采用扇形网格区域代替真实桨叶,并以该网格区域随时间的变化模拟桨叶旋转,建立了能够模拟桨尖涡生成和发展的非定常动量源法。结果表明,以准确桨叶力分布作为输入的动量源法能够得到较为准确的旋翼尾流,验证了桨叶几何模型对尾流的影响主要体现在桨叶力分布之上;而所建非定常动量源法对桨尖涡的模拟取得了较好的结果,且计算网格量及计算时间只有真实模型非定常模拟的1/8左右,具有更高的求解效率。

侵彻武器钻入地下爆炸产生的地震波在介质中传播特性较为复杂。针对钻地弹侵入地下爆炸后能量估算问题,基于反映高程差因子的萨道夫斯基修正公式,建立了不同地形状况下地下爆炸震源能量计算模型,并通过震源模型的计算结果得出爆炸能量。实例1对比传统的震源模型(6)与本文的震源模型(12)的计算结果发现该研究所提出的震源模型的精度远高于震源模型(6);实例2利用该研究的震源模型(13)针对测点不在同一水平面的情况,计算得到的地下爆炸能量结果有较高的精度。计算结果证明将爆炸振动的理论应用于计算钻地武器爆炸能量的方法是可行的。
