摘要
在考虑不同形状收缩段的基础上，建立描述不同形状拉伐尔喷嘴中沿喷嘴长各部气流行为的数学模型。数值计算表明，气体速度随入口段曲率半径的增大而增大，拉伐尔喷嘴和长度则随曲率半径的增大而减小。本数学模型可为不同形状超音速氧枪的设计提供理论依据。
A mathematical model describing the behavior of the flow in a De Laval nozzle with different configurations is developed. The numerical calculation results show that the gas velocities increase with the reduction of curvature and the length of laval nozzle decreases with the increase of the radius of curvature.The mathematical model can provide the theoretical basis for designing supersonic oxygen lance with different configurations.
