The micro jet experiment is under conditions of 3 different heights , 2mm , 3mm and 5mm of 2d ( 2 dimensional ) rectangle jet outlet and the width of each is same , 20mm . 5 reynolds numbers vary from 20 , 000 to 55 , 000 . the experiment characters tell that compared with that of the normal scaled jet flow , the dilution power of this micro jet becomes weaker
微射流实验在出口宽度固定为20mm情况下,选取了3种不同出口高度: 2mm , 3mm和5mm ,并通过改变速度使出口高度雷诺数在约20000到约55000之间改变,实验得到了流动图谱和微射流数学模型。
