摘要
本文用数值计算得到的数据集，回归出在变离心力场下，等截面管流由于热阻力引起的变密度流流量减少公式，并用热平衡法在旋转试验台上测量了加热条件下通道内的加热量和平均流速．由实验数据集回归出的流量减少公式与数值计算结果相符．
A mass flow decrease formula of a varying density heated gas flow in a tube with constant sectional area in varying centrifugal force field is presental in the paper by numerical analysis. By the use of thermo-balance method the heat and average flow rate in a heatal tube were measured on a rotating test rig. The experimental mass flow decrease formula is in good agreement with that from numerical analysis.
