In this paper, the model of six-degree-of-freedom electromagnetic tracking system is introduced. To promote the precision and stability of calculating an object's parameters, a new improved arithmetic is presented, which is a combination of the maximal ponderance of unit pointing vector tracking arithmetic and the eigenvector arithmetic. The correction is validated by the numerical simulation results...
The tubular pump device model including rotor, stator and inlet and outlet passages was simulated based on SIMPLEC arithmetic and standard k-?? RNG turbulence model. The match of rotor and stator in tubular pump was optimized. The numerical results show that the device model has a steady flow field and high efficiency when the distance between rotor and stator is 0.11D2. With the distance increasing...
As the thrust of wastewater treatment mixer is a blank in current research in domestic, hydrodynamic analysis on the blade of the wastewater treatment mixer was used in this paper based on lifting theory of fluid mechanics, and the calculation formula of hydraulic thrust was deduced and demonstrated, which is significant in theory and valuable in practice. After analysis, the hydraulic thrust of wastewater...
