The recently proposed short back extrusion (SBE) method is an improved immersed-type BE method. A translational concentric cylinder rheometer is used. As the measurement position is inside the sample, the upflow in the annular space is smooth even over a short distance (5 to 15 mm). Measurement over a short distance decreases the amount of sample adhering to the plunger; this facilitates repeated measurements, as the removal of the adhering sample after each measurement is not needed. The rheometer analysis program can perform automated Newtonian, power-law, and Herschel–Bulkley flow analyses by introducing novel mathematical solutions and obtaining constitutive equations for the various flow types. Herschel–Bulkley fluids exhibit semisolid properties and thixotropic flow characteristics, specifically, stress growth or time-dependent behavior. Currently, SBE viscometry is the only available method to evaluate viscosity and yield stress simply and simultaneously and this study presented the results compared with rotational cone-plate viscometry.

使用短反挤出粘度计分析 Herschel-Bulkley 流体的流动特性并考虑时间相关和应力增长行为

最近提出的短背挤压 (SBE) 方法是一种改进的浸入式 BE 方法。使用平移同心圆柱流变仪。由于测量位置在样品内部，环形空间中的上升流即使在短距离（5 至 15 毫米）内也很顺畅。短距离测量可减少粘附在柱塞上的样品量；这有助于重复测量，因为不需要在每次测量后去除粘附的样品。流变仪分析程序可以通过引入新的数学解决方案并获得各种流动类型的本构方程来执行自动牛顿、幂律和赫歇尔-布克利流动分析。Herschel-Bulkley 流体表现出半固体特性和触变性流动特性，特别是应力增长或随时间变化的行为。
