基于概率法的电力系统安全分析

为应对电力系统安全分析中的停机问题，基于概率法的方式，将常用的确定停机计算与加入了概率法的概率停机进行比较，研究了二者的区别与其在长期投资方向的不同。在进行电力系统停机分析时，通常会分别从确定停机与概率停机的角度出发，对其应急状态下的潮流进行计算。但前者的方法可能导致极低概率的停机事件被忽略，进而影响长期的资金投资。通过加入概率法的计算，使得对单个停机事件的判定由其具体的频率来确定，增加了系统运行的稳定性。     

Gluten-free cakes with walnut flour: a technological,sensory, and microstructural approach

Walnut flour (WF), a by-product of walnut oil production, is characterised by high polyunsaturated fatty acids, proteins, and fibre contents and presents suitability for bakery products. However, when using non-traditional ingredients, it is essential to evaluate the effect on the quality properties of the final product. So, this work aimed to assess the impact of WF on the technological, physicochemical, and sensory properties of gluten-free (GF) cakes. WF was added at a flour blend (cassava (CS) and maize (MS) starches and rice flour) at 0, 10%, 15%, and 20%. The results showed that WF modified starch gelatinisation, increased amylose–lipid complex (ALC) content, and made crumbs easier to chew. Besides, the total dietary fibre (TDF) and protein content significantly increased. Cakes with 15% WF presented the highest specific volume (SV) and no differences in overall acceptability with respect to control. Hence, WF is a suitable ingredient for gluten-free bakery products.

Impact behavior of aminosilane functionalized nanosilica based shear thickening fluid impregnated Kevlar fabrics

In the present work, two types of shear thickening fluids have been synthesized by using neat and aminosilane functionalized silica nanoparticles and their viscosity curves have been obtained by the rheometer. Based on the values of peak viscosity of synthesized shear thickening fluids, the surface functionalized nanosilica based shear thickening fluid has been chosen as a best candidate due to the high viscosity for impregnation into the neat Kevlar of different layers viz. four (04) and eight (08) layers for velocity impact study. The experimental investigations reveal high energy absorption of shear thickening fluid impregnated Kevlar as compared to the neat Kevlar. The maximum energy absorption 62 J is achieved corresponding to the initial velocity 154 m∙s⁻¹ for 08 layers shear thickening fluid impregnated Kevlar specimen. The data have also been analytically determined and validated with the experimental data. The experimental data have good agreement with the analytical data within the accuracy of around 15 to 20%. The present findings can have significant inferences towards the fabrication of shear thickening fluids using nanomaterials for numerous applications such as soft armors, dampers, nanofinishing and so forth.     

床温及SNCR脱硝对CFB锅炉NOx和N2O排放影响的试验研究

为了研究循环流化床（CFB）锅炉燃用无烟煤时床温及选择性非催化还原（SNCR）脱硝对于NO和N2O排放的影响，在1 MW CFB试验装置上开展了试验研究。结果表明:床温由880 ℃提高到970 ℃，NO排放质量浓度由119.5 mg/m3上升到226.0 mg/m3，N2O排放质量浓度由216.0 mg/m3降低到102.2 mg/m3；在氨氮摩尔比（NSR）为0~3.7之间，随着NSR的提高，脱硝效率从0上升到50.72%；进一步提高NSR到5.2，脱硝效率升至53.61%，增加较为缓慢；随着NSR从0提高到1.7，N2O排放质量浓度由84.3 mg/m3上升至118.3 mg/m3，增长较为缓慢；进一步提高NSR至2.0，N2O排放质量浓度上升至187.7 mg/m3，增长速度提高；继续提高NSR至5.2，N2O排放质量浓度上升至381.4 mg/m3；CFB锅炉采用以尿素为还原剂的SNCR脱硝工艺时，单纯通过加大NSR来提高脱硝效率不仅效果有限，过量喷入的还原剂会造成N2O排放量的显著提高。
