, 1990 本文采用三种不同加载方式(单轴拉伸,三点弯曲以及圆盘压缩)研究含微裂纹Al_2O_3的陶瓷的弹性性能及其抗拉强度.微裂纹是通过对材料瞬时突变加热和冷却(简称热冲击)形成的.试验结果表明:1)三点弯曲试验得到的力学性能参数较其它两种加载方式所得到的结果要稳定和集中.单轴拉伸试验结果分散性最大.2)热冲击温度越高,材料的等效弹性模量?和等效泊松比?以及各种加载方式下试件的抗拉强度??都有不同程度的下降.电镜观察证实了力学性能参数下降主要与材料内部微裂纹密度增加有关.3)Budiansky-O ...

, 2012 对高温熔融盐管壳式相变换热器进行了三维非稳态模拟研究。在考虑自然对流的情况下,模拟对比了直管式和弯管式相变换热的传热特性,考虑了流速、进口温度以及进口截面形状对储热性能的影响。结果表明,在熔化相同体积的相变材料的前提下,弯管可以缩短超过15%的熔化时间,换热特性明显优于直管系统。分析表明,弯管更好的换热特性主要是由于弯管内的二次流加强了换热,并且弯管也增加了换热面积。根据直管相变换热器与已有实验结果的对比显示模拟结果与实验结果有一定的差距,但是变化趋势一样 ...
