Numerical simulation on dense gas-particle riser flow   总被引：1，自引：0，他引：1  

Zha Xu-dong  Fan Jian-ren  Sun Ping  Cen Ke-fa 《浙江大学学报(A卷英文版)》2000,1(1):29-38

A turbulence gas-solid model that combines Eulerian approach and Lagrangian approach is formulated, which takes inter-particle interaction into consideration on the base of kinetic theory. The numerical algorithm is included. Comparison of the model results with the experimental results of Miller and Gidaspow (1992) showed good agreement. Project(59425004) supported by NSFC.  相似文献

一类高振荡随机哈密顿系统的李代数方法     

阮家麟  王丽瑾 《中国科学院大学学报》2019,36(1):5-10

为一类高振荡随机哈密顿系统提出一种李代数数值方法。对一个具体的高振荡随机哈密顿系统，给出两个基于李代数方法的数值格式，并证明它们近似保辛结构。通过数值实验展示这两种格式的根均方收敛阶，以及它们在数值求解该高振荡随机哈密顿系统中的有效性和优越性。  相似文献   

基于船舶领域的让路船决策分析     

朱凯歌  史国友  刘娇  汪琪  陈作桓 《上海海事大学学报》2019,40(3):26-31

为解决驾驶员使用最近会遇距离(distance of closest point of approach, DCPA)和最短会遇时间(time of closest point of approach, TCPA)进行避让决策时存在的忽略目标船参数的问题,采用Coldwell船舶领域模型并引入度量参数的方式,推导出具有时间序列的动态避让决策参数——最小缩放因子、领域侵入时间和领域侵入度。基于二分法和推导出的决策参数设计让路船决策流程,使用VC++MFC编程实现MMG模型仿真,并与基于传统DCPA和TCPA的避让决策仿真结果进行对比。结果表明,基于推导出的决策参数的避让决策能够解决基于DCPA、TCPA的避让决策忽略目标船参数的问题,具有预警时间精度高,避让时间短,避让转向角更合理等优势。推导出的决策参数在航线经济最优化和限制水域的避让决策方面都存在实用价值。  相似文献   

The validity and students’ experiences of peer assessment in a large introductory class of gene technology     

《Studies in Educational Evaluation》2014

Although studies have examined the validity of peer assessment, research including students’ own experiences of peer assessment is scarce. The present study aims to improve assessment practices in a context with a highly traditional assessment culture. The aim is first to examine the validity of peer assessment by analysing the compatibility of student and teacher evaluation and explore the differences between minor and major students’ evaluations. Second, the study examines students’ experiences of peer assessment. Peer assessment was implemented in a large bioscience course with 79 student participants. After the peer assessment, the students provided feedback. The results indicate that student subject understanding can be supported through a proper assessment practice. Peer assessment was successful in an introductory class with minor and major students, and most students experienced it as supportive of their learning.  相似文献   

Knowing the intentions,meaning and context of classroom assessment: A case study of Singaporean teacher's conception and practice     

《Studies in Educational Evaluation》2014

With the articulation of new ‘Holistic and Balanced Assessment’ initiatives in Singaporean schools, a new standard of conceptualising and enacting classroom assessment is expected of Singaporean teachers. This paper draws on findings from a larger study of ‘high-achieving’ Singaporean teachers’ deliberations and transactions of assessment activities. The use of case studies as a central methodology to investigate a contemporary phenomenon of education assessment extends the studies of conceptions and implementation of new classroom assessment practices in Anglophone and Western European countries. The findings from one of the ‘high-achieving’ case-study Singaporean teachers reveal that any quality assurance framework or guideline for evaluating teachers’ assessment practices needs to be sensitive to their intentions, meaning and context of teaching.  相似文献
