| 摘 要： | 利用一套以位移传感器为主的弹性平衡装置,测量几种不同表面形状设计的平板在充分发展的二维湍流边界层中的减阻效果,并对其减阻机理进行研究。结果表明,大涡破碎器 LEBU(Large Eddy Break-up)和其它减阻装置的形状和布置对表面摩擦阻力有较大影响,在有些设计状态下的平板得到了净减阻。

| Abstract: | Several manipulators were tested in fully developed two-dimensional turbulent boundary layer.The drag was mearsured directly by an elastic balancing dovicc composed main- ly with a displacement sensor.The efficiencies and principles of skin friction reduction were stu- died.The test results show that the shape and arrangement of LEBU(Large Eddy Breakup)and other devices have significant influence to the skin friction,and a net drag reduction appears in some cases. |
