机械工程师对不稳定流动状态下径流和轴流涡轮的性能是很感兴趣的,根据作者关于涡轮平均有效膨胀比(m.e.t.e.r)的设想,本文论述了该条件下预测涡轮性能的新方法,并提出了用数字计算机计算“脉冲系数”的程序。为了预测涡轮增压柴油机瞬时性能,在用实时数字计算机、混合计算机和模拟计算机进行模拟的过程中,作者成功地使用了这个方法,而且预测的结果和试验结果完全相符。
Mechanical engineers are very interested in the performance of run-off and axial-flow turbines under unstable flow conditions. According to the author’s idea about the average effective expansion ratio of the turbine, a new method for predicting turbine performance under this condition is presented and put forward Using a digital computer to calculate the “pulse factor” program. In order to predict the transient performance of turbocharged diesel engines, the author succeeded in using this method in simulations with real-time digital computers, hybrid computers and analog computers, and the predicted results were in good agreement with the experimental results.
