低密度风洞 meaning in English
low-density wind tunnel
Examples
- The tests were conducted in the hypersonic low density wind tunnel at nominal test conditions of mach 16 , stagnation temperature 923k , stagnation pressure 1 . 40mpa and 7 . 30mpa . heat - transfer data were obtained on a hemisphere model , a sharp cone and a big blunt cone respectively by means of infrared thermal mapping techniques , that of a 0 . 5mm thickness blunt cone by virtues of thermocouples . furth ermore , heat - transfer on all those models was calculated with the theoretical method
最后在名义m _ = 16 、 t _ 0 = 923k 、 p _ 0 = 1 . 40mpa及7 . 30mpa的高超声速低密度风洞中，利用红外热图技术获得了半球圆柱、尖锥、大钝头三个模型表面热流分布，利用薄壁法技术得到了一壁厚为0 . 5mm的钝锥模型表面的热流分布，并通过工程理论方法计算了模型表面的气动热，把理论计算结果与上述试验结果比较，几者符合得较好。
