    • Methods and devices for testing friction reduction systems are described herein. Embodiments of the disclosed devices allow direct measurement of fluid or rheological properties of friction reduction systems in a “one pot” or integrated device while maintaining the particles in suspension. In an embodiment, a device for testing a friction reduction system comprises an outer chamber. The device also comprises an impeller disposed at the bottom of the outer chamber for mixing the friction reduction system. In addition, the device comprises an inner chamber fixedly disposed within the outer chamber. The inner chamber has an inlet and an outlet such that the inner chamber is in fluid communication with the outer chamber. The device further comprises a bob rotatably disposed within the inner chamber.
    • 本文描述了用于测试摩擦减小系统的方法和装置。 所公开的装置的实施例允许在“一锅”或一体化装置中直接测量摩擦减小系统的流体或流变特性,同时保持颗粒处于悬浮状态。 在一个实施例中,用于测试摩擦减小系统的装置包括一个外室。 该装置还包括设置在外室底部的用于混合摩擦减小系统的叶轮。 此外,该装置包括固定地设置在外室内的内室。 内室具有入口和出口,使得内室与外室流体连通。 该装置还包括可旋转地设置在内腔内的摇摆杆。
