In this papar, the features of theoretical meshing of rotor with stator and its behaviors under operation of screw pair with different lobe ratios are analysed. It is considered that the differential pressure of a screw motor or pump is equal to the sum of differential pressure at the common screw meshing lines of all closed up chambers.

In this papar, the features of theoretical meshing of rotor with stator and its behaviors under operation of screw pair with different lobe ratios are analysed. It is considered that the differential pressure of a screw motor or pump is equal to the sum of differential pressure at the common screw meshing lines of all closed up chambers. It has been established through the study of hydraulic transverse forces that the conversion of the Equid pressure energy and the mechanical energy in the operating single-rotor system with different lobe ratios follows the law of conservation of energy. The form-ula of average torque given in this paper is based on the rational choice of differential pressure at the common screw meshing of closed chamber, including all the space-geometrical parameters. Some new concepts with respect to the mome-ntary equivalent meshing length of rotor with stator etc, for evaluating the influence of space-geometrical parameters are put forward. The feature of the two L_p/2 intervals of i>1/2 single-rotor systems that causes slanting torque M_s is discussed. The slant of rotor under operation of screw pair is believed to be resulted from all the transversal forces applied to the rotor.

Based on the conception of flow regime coefficient, f, and the asump-tion that the average torque exerted on the wall surface in an agitated vessel is approximately equal to that offered by the rotating impeller, a new shear rate model has been proposed: The model can be used for more broad area than before and the heat transfer correlation is more accurate. Plate paddles and a semiellipitical board impeller are investigated. For the two types of impellers, united correlations of both jacket side and coil side were obtained with 175 and 145 data plots, respectively. The correlations can be expressed:The data extended over generalized Reynolds numbers from 30 to 18600 and generalized Prandtl numbers from 40 to 6500. The average error of the correlations are 9.4% and 10.5%, respectively. The correlations can be used to design industrial agitated vessels.
