Walnuts (Juglans regia L.) are naturally rich source of many important nutrients which could be helpful in different food processing. Walnut mainly containing polyunsaturated fatty acids (PUFA), especially alpha linoleic acid (18:3n-3;9 g) and linoleic acid (18:3n-;38 g). Walnuts powder was fortified with commercial high gluten wheat flour (WF) into 4 composites flour from 10% to 40%. Walnut flour improves the nutritional value due to high protein and fat content, but affects the technological properties. Parameters such as functional, pasting and rheological properties demonstrated the influence of walnut reincorporation into gluten network. The interaction of walnut flour with wheat flour is a key factor which effects on the dough quality, causing thinning and weakening the gluten structure. Flour with 30% to 40% walnut substitution was more nutritious especially in relation to protein and monounsaturated fatty acid (MUFA), but responsible for more changes in technological characteristics of dough. Present study was also directed to examine the effect of moderate walnut consumption on lipids profile, enzymatic anti-oxidant (superoxide dismutase SOD and glutathione peroxidase GSH-Px) and lipid peroxidation (Melondialdehyde MDA) in rats fed with high-fat food. The Sprague Dawley rats were housed for five weeks and assembled into normal, high fat, high fat (HF) + 10% walnut, HF + 20% walnut, HF + 30% walnut and HF + 40% walnut. The lipid profile significantly improved especially by lowering the low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c) level increased in the group of HF + 40% walnut. The total anti-oxidant, SOD and GSH-Px activity were increased by supplementation of walnut and significantly higher in HF + 40% compared to the normal group. The Melondialdehyde (MDA) or lipid peroxidation status was increased in HF + 20% walnut to HF + 30% walnut as compared to normal and HF-fed diet but reduced by HF + 40% walnut. The

考虑了可控涡级内流面弯曲,通过寻找可控涡设计合适的轴向速度分布,采用给定压力分布求解环量分布的可控涡设计方法,首先对1.5级轴流亚声速试验涡轮进行了设计;然后进行参数化造型;最后运用三维黏性数值模拟,对所设计的1.5级涡轮进行了数值研究。数值结果表明:采用可控涡设计方法减缓了叶栅通道内的横向压力梯度;遏制了低能流体向吸力面堆积;消除了动叶栅根部沿径向方向的负压力梯度;降低了下通道涡涡核能量。与自由涡设计相比,可控涡设计涡轮效率提高了0.67%,功率提高了3.47%。研究还表明,采用这种压力可控涡设计方法,不仅可以提高动静叶匹配,还可以避免级后气流参数不均匀,最大程度地减少叶栅出口掺混损失。
