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 internal flow of a cross-flow fan was simulated with computation fluid dynamic(CFD), and the influence of the structure parameters of volute tongue on the performance of the cross-flow fan was analyzed. The relationship between the structure parameters of volute tongue and the flow filed of the cross-flow fan was presented and the shape line of the volute tongue was optimized. A new shape line...
A theoretical comparative study concerning performance of a constant flow hydrostatic thrust bearing having multi-circular recess and sector recess is described. The Computational Fluid Dynamics and the Finite Volume Method have been used to compute the characteristics of a constant fluid hydrostatic thrust bearing with circular and sector recesses. The performance has been compared, namely, recess...
Visual simulation of natural phenomena has become one of the most important research topics in computer graphics. Such phenomena include water, fire, smoke, clouds, and so on. Recent methods for the simulation of these phenomena utilize techniques developed in computational fluid dynamics. In this paper, the basic equations (Navier-Stokes equations) for simulating these phenomena are briefly described...
