摘要 首先应用粘流CFD数值模拟的方法评估了消涡轮的节能效果,然后从受力和流场的角度对消涡轮的节能机理进行分析,最后通过水动力试验对重新设计的消涡轮的节能效果进行了验证。发现消涡轮具有6%以上的节能效果,主要节能机理是加装消涡轮后,消除了螺旋桨的"毂涡",有效地降低了尾流的切向速度,消涡轮区域的阻力减小;并且,消涡轮可以产生一个与螺旋桨转矩方向相反的有利转矩。 CFD method for numerical simulation of viscous flow s is used to evaluate energy saving effect of vortex wheel, and energy saving mechanism is analyzed. An experiment was carried out to validate energy saving effect of a designed vortex wheel, with which more than 6% energy saving effect was gained. The vortex wheel can eliminate hub vortex in the wake of the propeller, decrease the magnitude of tangential velocity significantly, and reduce the propeller torque.
