Calculation of the Aerodynamic Drag for Middle-low Speed Maglev Train
Based on Navier-Strokes equation of the incompressible viscous fluid and Spalart-Allmaras turbulence model, external flow field characteristics of the CMS-04 low speed maglev train were investigated using the finite volume method. The aerodynamic drag with and without the horizontal wind were calcul...

| Summary: | Based on Navier-Strokes equation of the incompressible viscous fluid and Spalart-Allmaras turbulence model, external flow field characteristics of the CMS-04 low speed maglev train were investigated using the finite volume method. The aerodynamic drag with and without the horizontal wind were calculated at different speeds, the drag equations were deduced by the data and the differences were analyzed particularly. It reports that the air drag’s variations with the speed of the vehicle and the wind, can be provided for the calculation of the low-speed maglev vehicle traction. |
