| 6. | Upon the investigation on the domestic and foreign status of this issuse , and according to the situation of cefr , the detailed numerical analysis is performed using cfd software . the major researches are outlined as the following four aspects . 1 本文针对该问题的国内外研究现状,紧密结合工程建设的需要,应用cfd软件,对cefr的整个堆内过程进行了详细的数值模拟和研究,主要内容如下: 1 |
| 7. | A complicated model has been setted up to simulate the sodium flow in hot and cold plenum under normal condition and reactor scram of cefr , using fine grid to simulate the reactor internals and important equipments . this slove the problem that the simulation grids are very coarse in the precedeable work , and the accuracy and reliability of the simulation are improved . 4 对cefr的额定工况和全厂断电工况下的堆内过程进行了复杂的数学建模和分析,使用了精细的六面体网格,对堆内构件和重要的设备进行了三维的数值分析,克服了以往数值模拟中网格过于粗糙的缺点,使数值分析的准确性和可信度大大提高; 4 |
| 8. | In chapter 3 , an improved pca is presented which calculates the principal subspace of data collected from current time window and compares it with that from data collected under a normal condition . both the improved pca and conventional pca are used to monitor the tennessee eastman process , the improved pca has better performance to detect weak process changes 第三章提出一种改进主元分析法,在线检测当前时间窗口内过程数据的主元子空间,并与稳态无故障数据的主元子空间相比较,以判断是否发生了故障。 |
| 9. | Meanwhile some detailed researches are done on the deviation of gas in different load in tangentially - fired furnace which affords some significant directions in theory on the boiler ' s safely operation . simple method is employed in flow field prediction ; lagrangian method is used in the flow of particle and the radiant heat - transfer is simulated in monte carlo method . through summarizing these methods , the author develops a general program of large - scale power station with a friendly interface and post - disposal 本文对模拟炉内过程所采用的方法和模型进行了概括和总结,在此基础上综合这些方法和模型,如流场的计算采用的是simple方法,而颗粒相流动则是采用拉格朗日方法进行研究,辐射换热采用蒙特卡洛方法等,并且以这些模型和方法为基础,开发了大型电站锅炉的通用程序,并包括友好的界面和后处理。 |
| 10. | After analyzing , the author got the basic character of tidal flat hydrodynamic : the time of flooding on bare flat and ebbing is basically the same and the time of flooding on pioneer zone of salt marsh is a little short ; the process curve of current speed on bare flat did not appear peak value on the beginning of flooding and at the end of ebbing but presented double peak , that is , it presented double peak in winter and spring and ebbing peak value disappeared in summer and autumn , salt marsh presented single peak character in a year and the process curve in tidal creek presented double peak ; all current direction on every spot presented gyration current and the current speed changed rapidly during the high water level without obvious slack water period 分析得到了潮滩水动力基本特征:光滩水位涨潮和落潮时间基本相等,而盐沼前缘带水位涨潮时间略短;光滩流速过程线在涨潮初和落潮末出现峰值,呈现“双峰型”特征,盐沼前缘带则冬、春季节呈现“双峰型” ,夏、秋季节落潮峰值消失,盐沼带四季呈现单峰特征,潮沟内过程线为“双峰型” ;各测点流向均呈现回转流特征,在高水位时流向迅速改变,不存在明显的憩流。 |
