在过去的十年中，旋转流变学中复杂几何图形的使用有了显著的增长。本文综述了近几年来此类几何在流体食品流变学测量中的理论和应用技术进展。综述的应用包括复杂流体的流变特性、放大分析和混合或反应堆单元过程的模拟。详细讨论了克服与使用复杂几何结构相关的主要限制的新技术，即模糊定义的剪切率。使用复杂的几何形状获得流变学测量在流体食品分析中提供了许多好处，有助于改进产品特性并提供以前无法测量的数据。
There has been significant growth in the use of complex geometries in rotational rheometry over the last decade. This article reviews the recent technical advances in both the theory and application of such geometries in the rheological measurement of fluid foods. Applications reviewed include the rheological characterization of complex fluids, scale-up analysis and the simulation of mixing or reactor unit processes. Novel techniques to overcome the principal limitation associated with use of complex geometries, namely ill-defined shear rates, are discussed in detail. Obtaining rheological measurements using complex geometries offers numerous benefits in fluid food analysis, facilitating improved product characterization and the provision of previously unmeasurable data.
