A tubular rheometer was proposed for testing rheological properties of heterogeneous two-phase systems flowing through a pipe. The paper describes the idea of its design and assembly in a flow system. The research methodology and guidelines for interpretation of measurement data are given. Based on the study performed for the water-oil system, it was demonstrated that the use of standard rotational rheometers could not provide similar measuring possibilities. It was possible to determine the rheological characteristics of unstable two-phase mixtures and variability in viscosity in the conditions of actual flow. The interpretation of the measurement results also provided unusual means to identify the phase inversion phenomenon. The areas of application of the proposed method extend beyond research of water-oil systems and scope of experiments reported in this paper. Despite the focus on a specific mixture and its exceptional characteristics, the study also demonstrated other areas of application of this method.

提出了一种管式流变仪，用于测试流经管道的异相两相系统的流变特性。本文介绍了在流量系统中进行设计和组装的想法。给出了解释测量数据的研究方法和指南。根据对水油系统进行的研究，结果表明，使用标准旋转流变仪无法提供类似的测量可能性。在实际流动条件下，可以确定不稳定的两相混合物的流变特性和粘度的变化。对测量结果的解释还提供了识别相位反转现象的不寻常手段。所提出的方法的应用范围超出了水油系统的研究范围和本文报道的实验范围。尽管着重于特定的混合物及其非凡的特性，但该研究还证明了该方法的其他应用领域。
