Experimental and numerical investigations are conducted to study the effect of the grooved width of a grooved casing on the performance of a compressor.
采用试验与数值手段研究周向凹槽槽宽变化对压气机性能的影响,在一亚声速转子上进行3种不同槽宽的周向槽处理机匣试验。
International Society for Rock Mechanics ( ISRM ) proposed in 1995 a new type of rock fracture toughness specimen棗cracked chevron notched Brazilian disk ( CCNBD ), the previous analytical and numerical studies of the dimensionless stress intensity factor, which is an important mechanicel parameter, does not take into account the effects of finite notch width.
国际岩石力学学会(ISRM)在1995年提出一种新型的岩石断裂韧度试样——人字形切槽巴西圆盘试样(cracked chevron notched Brazilian disc——CCNBD),对该试样的一个重要力学参数即最小无量纲应力强度因子的标定,以前的分析和计算都没有考虑切槽宽度的影响。
