从真实流体所具粘滞耗散特性出发,以数学解析法严谨地论证了淹没射流因沿程能量通量渐减,加以其动量通量沿程守恒,故其质量通量必然沿程递增,从而衍生出射流卷吸及附壁效应,于是,在专门设计的腔体中就会发生流控振荡现象.发生流控振荡的腔体的两个出口会交替地输出两股非共面动量通量射束并在其后形成顺流螺旋涡,在绕水平轴旋涡的流场中,重于水的沙粒将获得附加的悬浮功增量,而轻于水的气泡或藻菌团的上浮行动将受阻碍.前者会加大河流的挟沙能力,后者的影响将导致水藻所赖以滋长的光合能量锐减而枯萎,从而改善水质.
Based on the viscous dissipative properties of the real fluid, the mathematic analysis method is used to rigorously demonstrate that the submerged jets are gradually decreasing along the energy flux, and their momentum flux is conservative along the path. Therefore, the mass flux inevitably increases along the path, Resulting in the entrainment of the jet entrainment and the Coanda effect, so flow-controlled oscillations occur in specially designed cavities.The two outlets of the cavity where the flow-controlled oscillations occur alternately output two non-co-planar momentum fluxes The amount of beam followed by the formation of spiral whirlpool in the vortex around the horizontal axis of the flow field, heavier than water sand will be an additional amount of suspended work gain, while lighter than water bubbles or algae cluster floating The former will increase the sediment carrying capacity of rivers and the latter will cause the photosynthetic energy that algae grows to wither sharply and wither, so as to improve water quality.
