| Abstract: | On the basis of viscous fluid mechanics and the theory of ro- tor dynamics,both the slippages within the clearances and the forces exer- ting upon rotors of an elliptical gear flowmeter are analyzed in this paper. Theoretical models for predicting the effects of fluid viscosity on the error characteristics and pressure loss of the flowmeter have also been developed herein.The calculated results showed a good agreement with the experimental data. |
