8818698 Greenspan This project is concerned with the study of the centrifugal separation of mixtures. The effects of geometry, particle size variation, collisional processes, flow stability and vorticity production will be examined. Numerical simulations will also be completed, tested and employed. The objectives of this project are (1) to achieve an understanding of fundamental phenomena involving rotating two-phase fluids especially those amenable to laboratory study and verification; and (2) to develop in the shortest possible time of a solid and sound basis for technological application, exemplified by a new separation/fractionation centrifuge.

这个项目是关于混合物离心分离的研究。几何形状、粒度变化、碰撞过程、流动稳定性和涡量产生的影响将被检查。数值模拟也将完成、测试和应用。该项目的目标是：(1)了解涉及旋转两相流体的基本现象，特别是那些适合实验室研究和验证的现象；(2)在最短的时间内开发出以新型分离/分馏离心机为例的技术应用的坚实基础。
