本文依据Reynolds湍流方程,从理论上阐述了湍流度对流体运动物理量的影响。并根据在低速风洞中,对平板边界层、机翼、球体、垂直流平板的绕流,以及Pitot静压管测速等,在不同湍流度下的试验结果,应用科学归纳法,论述了湍流度对绕流物体气动力特性的影响。最后对湍流度研究的工程实际意义,提出进一步的看法。 Based on the Reynolds turbulence equations, this paper theoretically expounds the influence of turbulence on the physical quantities of fluids. According to the test results under different turbulence degrees in the low-speed wind tunnel, using the scientific induction method, turbulent flow is discussed based on the flow around the slab boundary layer, wing, sphere and vertical flow plate, Effect of Degrees on Aerodynamic Characteristics of Flow Around Objects. Finally, the actual significance of turbulence research project, put forward further views.
