This paper investigates the thermal performance of a three-phase 10kW flux-switching permanent magnet (FSPM) machine used as an integrated starter generator (ISG) for hybrid electric vehicles, where the temperature rise experiments are conducted under different operating conditions. Also, the thermal analysis of the FSPM machine is simplified into one-dimensional steady heat conduction with two heat...
The aerodynamic characteristics directly affect driving characteristics, stability, operation, oil consumption, and safety of automobiles. The virtual wind tunnel experiment simulation based on finite element method has provided useful theoretical reference to automobile bodywork design. In this study, the air flow and distribution information around the automobiles was obtained using aerodynamic...
The thermodynamics of the exhaust gas recirculation (EGR) cooler is very important for reducing oxides of nitrogen (NOx) emission of diesel engines. Using the CFDesign software, some 3-D fluid thermodynamic models of EGR coolers are established by using the finite element method (FEM); and the temperature, velocity and pressure fields of fluids in the EGR coolers are simulated and verified by experiments...
Blockage of hollow strands' waterway can cause cooling-water flux decreasing, cooling effect falling and stator bar overheating in water-cooling turbo-generators, which could induce generators not to operate normally. It helps to calculate precisely temperature field of generators and diagnose incipiently the plugging fault of cooling-waterway that one study fluid characteristic of cooling-water on...
The finite difference method is adopted to compute the axial velocity of coal water slurry (CWS) pipeline transport axial flow field flowing in the laminar flow, which could be described by Poisson partial differential equation. In this work, the finite difference method was used to compute the computational axial velocity. The axial velocity contour of CWS pipeline axial flow field was presented...
This paper introduces a new computational technique-solid cellular automaton-for the solution of physical field. The thought of cellular automaton comes from the self-organization theory in biology. In this theory, the state of a cell is determined by the states of itself and its neighbors. The information outside the neighbor domain does not contribute to the state of the cell. The global analysis...
