Measurement of Momentum Transport From Non-Evaporating Particles in High Turbulent Intensity Flows

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体的动量输运。试验装置将产生准均匀湍流场。将测量平均和脉动速度，以及湍流的时间和空间积分尺度。确定了悬浮在湍流场中的固体球上的阻力，得到了在更宽的湍流长度尺度-颗粒雷诺数域内阻力系数的表达式。这项工作与建模相关，在化学和材料处理、固体运输和燃料喷雾等不同领域中都有应用。***

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. ***
