초록정보

The reciprocal action between the object in a flow channel and the flow field is widely used in industry but research has not been made on this subject. In this study, a numerical method, the SIMPLE applied to the flow problem of a cylindrical channel with object lying at the channel under line. The flow characteristics were analyzied under the condition that the geometry of the flow channel is fixed and the Reynolds number and the geometry of the object are varied. The equations governing the laminar flow of an incompressible, steady fluid were solved numerically. The grid size was optimized to reduce the truncation error at the regions of a complicated velocity distribution. The SIMPLE algorithm and the hybrid scheme are adapted to this study. From the numerical results the characteristics of the velocity-, pressure-distributions, drag force and channel pressure drop were discussed. It was disclosed that the drag force increases, when channel pressure drop and total volume of the object are fixed, as the shape of the object becomes less slender.
