摘要：

采集海底矿石颗粒是开发深海矿产资源的核心技术.基于康达效应的附壁射流式集矿技术被认为是一种具有工程应用潜力的集矿方法.基于实验验证的计算流体力学-离散元(CFD-DEM)数值模拟方法,以提高矿粒采集率为优化目标,开展集矿装置几何参数优化研究.探究集矿装置凸曲壁曲率半径与矿粒直径之比(R/d)、射流切向弧度(θ)和射流厚度与矿粒直径之比(b/d)对临界无因次射流流量(q₀)的影响规律,并对各参数影响的显著性进行了比较.同时,结合集矿流场流速分布特征阐释矿粒受力运动特性.研究结果表明,b/d对集矿效率的影响最大,R/d次之,θ的影响最小.对比工况中,当R/d = 9、θ = 1.05 rad、b/d = 0.26时,矿粒采集效果最佳.本研究可为设计研发高效低扰动集矿装置提供理论支撑.

Abstract:

The collection of seabed ore particles is a core technology of exploiting deep sea mineral resources, with wall-attached jet collection technology based on Coandă-effect being considered as a nodule collection method with engineering application potential. Based on the experimentally verified CFD-DEM numerical simulation, the optimization of geometric parameters of the collection device is conducted to improve pick-up efficiency. The influences of three geometric parameters, i.e., the ratio of the curvature radius of the convex curved wall to the diameter of the nodule particle R/d, the tangential radian of the jet θ, and the ratio of the thickness of the jet to the diameter of the nodule b/d on the critical unconditional jet flow rate q₀, are investigated and compared. The nodule collection characteristics are revealed through an analysis of the flow field characteristics. The results show that b/d has the greatest influence on the pick-up efficiency, followed by R/d, while θ has the least. The performance of nodule collection is optimal when R/d=9, θ=1.05 rad, and b/d=0.26 in contrast conditions. This research provides technical support for designing and developing the Coandă-effect-based collection devices.

Key words: polymetallic nodule, Coandă-effect-based collection, computational fluid dynamics-discrete element method (CFD-DEM), nodule pick-up efficiency, parametric optimization
