The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.
对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析,结果表明:直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率;直壁型无叶扩压器使得叶轮出口的流动出现分离;扩压器的形式对离心叶轮的整体气动性能影响并不大;在进行离心叶轮数值研究时,叶轮后的延伸区最好采用等面积无叶扩压器,以尽量减小无叶扩压器所引起的计算误差。

As compared with the traditional irrigation-traditional fertilization, the following results of the improved optimized irrigation-optimized fertilization were obtained: significantly higher nitrogen use efficiency; the like tiller number per unit area, percentage of the tiller ear number/the tiller number, the ear number per unit area, the greatly reduced grain number per ear, and significantly heavier weight of 1, 000 grains; a trifle taller plants; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; almost the same LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; a little longer flag leaf, 2〓 leaf, 3〓 leaf (but the three leaves were shorter than those of the optimized irrigation-traditional fertilization) and shorter 4〓 leaf from top, a bit reduced total area of these leaves; almost the same leaf thickness, mean canopy leaf tilt angle, light extinction coefficient , ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and fair plant type; almost the same senescence process of flag leaf; and increased root amount in 0-120cm soil layer and smaller rate of progressive decrease of the root length density and root weight density with soil getting deep, which can strengthen the resistance to adverse conditions such as water stress in the later stage.
在优化水肥条件下,冬小麦总分蘖数、成穗率及单位面积穗数与传统水肥比较接近,但穗粒数显著减少,千粒重显著提高;株高稍有增加;基部节间长度缩短,充实度略微增高,穗下节间增长;中后期LAI与传统水肥的LAI值基本吻合;起身至成熟干物质积累量动态变化过程与传统水肥十分接近,但抽穗至成熟所形成的干物质量增加;上三叶变长(但上三叶长度增加幅度小于优化灌溉-传统施肥处理),倒4叶变短,总叶面积略有减少;叶片厚度、冠层平均叶倾角、消光系数、冠层各层的透光率与传统水肥差异很小,株型较好;旗叶叶绿素含量动态变化与传统水肥十分接近;0-120cm土层的总根量明显增加,上层根群和深层根群的差异最小,有利于提高小麦后期的抗逆力。
