US-Czechoslovak Research on Solid-Liquid Flow

俄亥俄州立大学的Robert S.Brodkey博士和捷克技术大学的Ivan Fort博士的这项美国-捷克斯洛伐克合作研究项目的主要目标是制定和测试更好的固体运输问题的理论方法。特别令人感兴趣的是，当用来描述固体颗粒运动时，力平衡中浮力项的定义。研究人员打算测量液体和固体在两相、稠密的固液混合物中的湍流波动。他们将使用不可见和有标记的颗粒来实现对颗粒之间流动湍流的光学诊断。粒子运动和流体运动都要绘制地图，以便与捷克斯洛伐克合作伙伴开发的理论中的粒子预测进行比较。结果应该会给出关于湍流的新数据，无论有没有颗粒，并可能解决关于浮力在运动方程中的作用的理论争议。这个流体动力学研究项目通过使美国和东欧的专家能够结合互补的人才，并在具有强烈共同兴趣和能力的领域汇集研究资源，实现了促进科学知识发展的计划目标。

The primary objective of this U.S.-Czechoslovakia cooperative research project between Dr. Robert S. Brodkey of Ohio State University and Dr. Ivan Fort of the Czech Technical University is to formulate and test better theoretical approaches to problems of solids transport. Of particular interest is the definition of the buoyancy term in a force balance when used to describe solid particle motion. The researchers intend to measure the turbulent fluctuations of both liquid and solid in a two-phase, dense, solid-liquid mixture. They will use invisible and marked particles to enable optical diagnostics of the flow turbulence between particles. Both particle motion and fluid motion are to be mapped, for comparison to particle predictions from a theory developed by the Czechoslovak partner. Results should yield new data on turbulence flow, with and without particles, and may resolve a theoretical controversy about the role of buoyancy in equations of motion. This project in fluid dynamics research fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence.
