, 2013 从能量守恒角度,利用傅里叶分析方法,研究了离散形式下对流项和黏性项对动能变化的不同作用,指出了在对流项处理得当的条件下,黏性项的计算偏差是导致计算失稳的主要原因,并提出了利用人工黏性弥补这一计算偏差的方法。以四阶中心基本离散格式为例,说明了八阶人工黏性施加方法,人工黏性项含有一个可调参数,这个参数可以根据基础格式计算出的耗散与真实耗散的偏差确定出最大值与最小值,也给出了确定最优参数的准则。与其他人工黏性方法的不同在于,(1 ...

A Study of Viscosity and Bleeding Properties of Solidified Bentonite-Cement Mixtures
, 2010 本研究使用皂土和普通波特蘭水泥配合成各六種配比， 再以四種攪拌葉片(2.5~ lOcm) 、三種攪拌速率(1200~2400rpm)與水進行拌合，研究其黏度或浮水與時間的關 係，少數配比並以爐石粉取代部份水泥以觀察爐石粉對黏度及浮水的影響。研究結果 顯示: (1)黏滯性:皂士或水泥的含量愈高，其黏度愈高:以皂土含量由4% 增至6% 為例， 在300分鐘前其黏度可提高3 . 3 倍以上:而水泥含量由16%增至20%的結果顯示，其 黏度亦可增加1. 3 倍以上。而攪拌速率的增加和葉片的增大均有助於黏度的發展，
