Experimental Study on Mixing and Explosive Properties of Liquid Oxygen and Kerosene
In order to study the mixing and explosion characteristics of liquid oxygen and kerosene,a partial confined space test system is established to simulate the application scenarios of the launch site and the tests are carried out. It is demonstrated that when liquid oxygen and kerosene are discharged and mixed at the same time,the concentration of kerosene and oxygen increases at first and then decreases. When kerosene temperature is 65℃ and ignition excitation is 5.9J,even if liquid oxygen leaks,the ignition and explosion condition are still not reached at the measuring points arranged above the liquid level. In the test when the kerosene temperature is raised to 80℃,explosion occurs when liquid oxygen is released only for about 20 seconds. At ignition time,the concentration of kerosene,oxygen,and nitrogen are 1.31％,40.05％ and 58.64％ respectively,and the ratio of kerosene concentration to oxygen concentration is 0.033.
