摘要
通过对涡流管的热力分析和流动分析，建立其内部过程的数学模型。从速度场的变化推导内部热分离的温度方程。实验系统测量涡流管内部温度场及速度场，理论计算值与实验值吻合。
A model of the interor process of vortex tube is deduced on the basis of analyzing the thermodynamic properties and flow patterns,The temperature eguation of heat separation is induced from the change of Velocity field The temperature field and the velocity field are measured with the experimental system.The experimental results are consistent well with the theory calculation results.
