Three-dimensional numerical simulation is carried out to investigate the flow and heat transfer characteristics of impingement/effusion cooling systems. The impingement/effusion holes are arranged on two parallel perforated plates respectively in a staggered manner. Every effusion hole has an inclined angle of 30° with respect to the surface. The two parallel plates are spaced three times the diameter...
This paper presents a novel dual-stator hybrid excited synchronous wind generator (DSHESG). The structure characteristics are presented and no-load magnetic field is computed by 3-D finite element method. Static characteristics including magnetic flux density, EMF, inductances are analyzed. A closed-loop control system for field windings using PWM method is built on the basis of mathematical model...
The structure and operation principle of a novel hybrid excitation claw-pole synchronous machine (HECSM) are introduced. The field-control capability based on the equivalent magnetic circuit method is analyzed. A 3D finite element analysis (FEA) is used to analyze no-load magnetic field distributions, air-gap flux, phase flux linkage and back EMF variation for different field currents. Furthermore,...
SF6 gas insulated transformer (GIT) has the advantages of nonflammable and non-explosive. However, there is a deviation in flows near the coils, which results the coil temperature overheat. In order to remove the deviation of flow, it is necessary to use force-directed-gas duct cooling system. In this paper, the force-directed-gas duct heat fluid coupled finite element method is presented based on...
A novel dual-stator hybrid excited synchronous claw-pole generator (DSHESG) is proposed in this paper. The structure characteristics are described and the operation principle is introduced. Using finite element method, the field-control capability of DSHESG is studied. Some static characteristics including air gap flux density, no-load flux linkage, back-EMF, self-inductance of field windings, and...
