逆马格努斯效应是一种现象，其中旋转的球体经历与传统马格努斯效应相反的升力。这种效应通常在高于临界雷诺数或自旋比的流动中观察到。实验研究了旋转球体在含有微米级悬浮液滴的流动中的逆马格努斯效应。升力是通过将液滴注入封闭的回流风洞中来测量的。我们研究了几种类型的分散液滴的逆马格努斯效应的阈值。我们的研究结果表明，悬浮水滴的流动显着影响逆马格努斯效应的发生，导致临界雷诺数和自旋比的下降。
The inverse Magnus effect is a phenomenon in which a spinning sphere experiences a lift force opposite to the conventional Magnus effect. This effect is typically observed in the flow higher than a critical Reynolds number or spin ratio. We experimentally studied the inverse Magnus effect on a spinning sphere in a flow containing suspended micrometer size droplets. The lift force was measured by injecting droplets into a closed return wind tunnel. We investigated the threshold of the inverse Magnus effect for several types of dispersed droplets. Our results indicate that the flow with suspended water droplets significantly affects the onset of the inverse Magnus effect, causing a decrease in the critical Reynolds number and spin ratio.
