ABSTRACT CTS-9421949 G. Ruff An experimental investigation to evaluate the momentum transport of non-evaporating solid spheres in a turbulent flow will be undertaken. A test Facility will produce a quasi-homogeneous turbulent field. The mean and fluctuating velocities, as well as the temporal and spatial integral scale of turbulence, will be measured. The drag force on a solid sphere suspended in the turbulent field will be determined, and the expression for the drag coefficient within a broader turbulence length scale-particle Reynolds number domain will be obtained. The work has relevance for modeling, with applications in various areas such as chemical and materials processing, solids transport, and fuel sprays. ***

摘要 CTS-9421949 G. Ruff 将进行一项实验研究，以评估湍流中非蒸发固体球的动量传递。 测试设施将产生准均匀湍流场。 将测量平均速度和脉动速度，以及湍流的时间和空间积分尺度。 将确定悬浮在湍流场中的固体球体上的阻力，并获得更广泛的湍流长度尺度-粒子雷诺数域内的阻力系数的表达式。 这项工作与建模相关，可应用于化学和材料加工、固体输送和燃料喷雾等各个领域。 ***
