SPP 1018: Analyse, Modellbildung und Berechnung mehrphasiger Strömungen

该研究计划致力于气体在牛顿或非牛顿液相中分散的稳定和非稳定流动。流动系统可由可分散固体颗粒的混相或非混相组分组成。由于这种流动系统在技术和工业过程中大量出现，因此研究仅限于常用的设备，如：无内部装置的气泡塔，循环反应器和加气搅拌容器。研究应集中在以下主题上：—开发和测试新的仪器，用于时间相关的两个阶段的三维测量，这可以为改进物理理解和与质量，动量和热量的传输过程相关的模型开发提供实验结果。开发和验证分析和数值计算方法，以便更好地设计和优化相关技术系统。

The research programme is devoted to steady and unsteady flows with gases being dispersed in a newtonian or non-newtonian liquid phase. The flow system may consist of miscible or immiscible components where solid particles may be dispersed. As a result of the numerous occurrence of such flow systems in technical and industrial processes the research is restricted to the commonly used equipment as there are: bubble columns without interior installations, loops reactors and aerated stirred vessels. The research should concentrate on the following topics:-- Development and testing of new instrumentation for time-dependent, three-dimensional measurements of both phases which can provide experimental results for an improved physical understanding and model development related to transport processes of mass, momentum and heat.-- Development and validation of analytical and numerical calculation methods which allow for a better design and optimisation of relevant technical systems.
