在实验室条件下，制作了模拟膛口高速射流的装置。
A simulated set up of high speed simulated exhaust muzzle flow field is made up.
射流的偏转角主要受阀口角度的影响，几乎与阀口尺寸无关；但射流的收缩系数则与两者都有关系。
The deflection angle of injection mainly depends on the valve port angle and almost has no relation to the valve size, but the reduction coefficient vavies with both of them.
实验结果表明，燃烧器区射流一出口就出现了贴壁，燃烧区及燃尽区壁面附近涡量强度和湍动度都很高。
The results of an experimental investigation indicate that there emerges a wall attachment phenomenon as soon as the jet flow at the burner zone reaches its outlet. Furt...
