INFLUENCE OF WIND ON AERODYNAMIC DRAG FOR THE SECOND CASE OF THE ARRANGEMENT OF THE EQUIPMENT ON THE LE 060EA LOCOMOTIVE BODYWORK

Influence of wind on aerodynamic drag for the second case of the arrangement of the equipment on the LE 060EA locomotive bodywork

The electric power supply equipment of electric railways vehicles of surface is placed on the their body.The arrangement of the equipment on the vehicle body determines the variation of the aerodynamic drag.The gusts of wind occurring during the vehicle movement result in additional requests.The case of the locomotive of type LE 060 EA Cast 5100kW

An operational improvement of A-4DEnVar and its application to the estimation of the spatially varying bottom friction coefficients of the M2 constituent in the Bohai and Yellow seas

The analytical four-dimensional ensemble variational (A-4DEnVar) data assimilation scheme inherits the advantages of the conventional four-dimensional variational (4D-Var) data assimilation scheme and 10.13 removes the adjoint model.However, compatible operational improvements such as the reduction of the computational costs and the localization me
