Computation of drag and lift coefficients for simple two-dimensional objects with Reynolds number RE=420 000
Original language description
The article deals with comparison of drag and lift coefficients for simple two-dimensional objects,which are often discussed in fluid mechanics fundamentals books. The commercial CFD software FLUENT 13 was used for computation of flow fields around the objects and determination of the drag and lift coefficients.The flow fields of the two-dimensional objects were computed for velocity up to 160 km per hour and Reynolds number Re=420000. Main purpose was to verify the suggested computational domain and model settings for further more complex objects geometries. The more complex profiles are used to stabilize asymmetrical ('z'-shaped) pantographs of high-speed trains. The trains are used in two-way traffic where the pantographs have to operate with the same characteristics in both directions. Results of the CFD computations show oscillation of the drag and lift coefficients over time. The results are compared with theoretical and experimental data and discussed. Some examples are presente
