试验本体采用了透明的垂直环形通道,电加热元件的尺寸及形状与核燃料元件相同。
The test section was composed of transparent vertical annuluses. The shape and size of electric heating rods were similar to nuclear fuel rods.
在相对升程小于6%、压比小于0.7后,环形通道的末端将产生激波,激波带来较大的全压损失。
At the end of the annular passage, shock wave occurs when the relative lift is less than 6% and the pressure ratio is less than 0.7, which causes a greater total pressure loss.
空气进入干燥器之后需通过环形通道,环形通道采用聚四氟乙烯涂层,防止雨水、灰尘和昆虫等进入。
Air enters the desiccator through an annular inlet channel, which is covered by a strip of Polytetrafluorethylene PTFE coated wire mesh to prevent the ingress of rain, dust, insects, etc.
