This paper deals with design of a new protective structure and completes the first step resulting to the preliminary draft of its shape and structural design. The process of designing the protective structure started with creation of the computational model solved in the software environment Ansys Fluent, where the most common cuboid shape of protective structure was assessed on the bases of output...
The aerodynamic characteristics directly affect the stability, driving characteristics, safety, operation, and oil consumption of automobiles. This study examines the aerodynamic drag force acting over the car body using CFD analysis and results were validated experimentally by conducting the wind tunnel test. The drag force acting over the car body is determined by both numerical and experimental...
Contemporary vehicles are required to yield superior performance with low emissions, high stability, and a high fuel economy. For the same power output, the speed of the vehicle can be increased by reducing the drag force, which is resistance to the forward motion. Under-body region of the vehicle is often neglected because of its complex geometry and the presence of uneven and cleft structures which...
Viaducts are widely built in the modern high speed railway system. The noise barrier will have some effect on the aerodynamic characteristics of the high speed train running on the double line viaduct. It is essential that the research on this effect will be made. It will provide some engineering reference for the high speed railway construction. Using the CFD(Computational Fluid Dynamics) soft Fluent,...
