摘要

摘要研究了在雷诺数 Re=105 条件下，通过在气缸后面放置一块平板来减少气缸阻力的被动方法。论文介绍了 ANSYS Fluent 对圆柱体-平板系统周围流动的模拟结果，包括速度场和压力场、流线、阻力系数以及圆柱体表面分离点位置与平板相对长度的关系。研究发现，与孤立的气缸相比，气缸-板系统的阻力系数可降低约 40%。

DRAG COEFFICIENT OF A CYLINDER WITH A FLAT PLATE PLACED BEHIND IT

Abstract

A passive method for reducing the drag of a cylinder by placing a flat plate behind it at a Reynolds number Re=10⁵ has been studied. The paper presents the results of an ANSYS Fluent simulation of the flow around a cylinder–plate system, including the velocity and pressure fields, streamlines, and the dependences of the drag coefficient and the position of the separation point on the surface of the cylinder on the relative length of the plate. It has been found that the drag coefficient of the cylinder–plate system can be reduced by approximately 40% compared to the case of an isolated cylinder.
